Post-Surgical Pain

What is Post-Surgical Pain?

Post-surgical pain is pain that develops after an operation because of the surgical injury to skin, muscle, bone, nerves and other tissue. Roughly 75% of people who have surgery have acute pain afterward, often moderate to severe, and fewer than half report adequate relief.^[1] For most people it eases as the body heals, but pain that continues past the expected healing time is called chronic postsurgical pain.^[2]

Common symptoms

Early post-surgical pain is felt at and around the surgical site and is usually worse with movement, coughing or deep breathing. Soreness, swelling and stiffness often go along with it.^[1]

Chronic postsurgical pain affects about 10% of patients who have surgery. It typically begins as acute pain that was hard to control and often has neuropathic features such as burning, shooting or electric-shock sensations.^[2]

Causes and risk factors

Acute pain comes from tissue injury and the inflammation of healing. Persistent pain is more likely when acute pain is poorly controlled, and nerve injury during surgery is a common contributor.^{[2, 3]}

A meta-analysis of 33 studies found that younger age, female sex, smoking, depressive or anxiety symptoms, sleep difficulties, higher body mass index and pain before surgery were each linked to worse pain control in hospital.^[4]

How it is diagnosed and treated conventionally

Post-surgical pain is assessed by your surgical and anesthesia teams from your pain scores, your recovery and the type of surgery. Persistent pain needs a medical evaluation to rule out causes such as infection, a complication or nerve injury.^[1]

Treatment now emphasizes a multimodal approach: several kinds of pain medicine, local or regional anesthesia, and early movement, with the aim of lowering opioid use because of the risks of opioid misuse.^[1] Poorly controlled pain can slow recovery and raise the chance of long-term pain.^[3]

Why Post-Surgical Pain calls for a whole-person approach

Pain after surgery is shaped by more than the incision. Tissue injury, nerve sensitivity, mood, sleep and general health all affect how much pain a person feels and how long it lasts.^{[2, 4]}

Supportive care that addresses these factors may help a person move, sleep and take part in rehabilitation, which are the goals of the surgical team as well.

Inflammation and tissue healing

Inflammation is a normal part of healing, but ongoing inflammation around a wound or joint adds pain and stiffness. Researchers who study acupuncture's effects on pain look at inflammatory signaling molecules as one possible target.^[5]

Nerve sensitivity

Chronic postsurgical pain often has neuropathic features, and it is described as unresponsive to opioids.^[2] Patients who are more sensitive to pain before surgery, for example those with lower pressure pain thresholds, tend to have more pain afterward.^[6]

Stress, mood and sleep

A history of depressive or anxiety symptoms and sleep difficulties were each associated with poor pain control after surgery in a pooled analysis.^[4] This is one reason stress, mood and sleep are part of the conversation in complementary care.

Bowel recovery and nausea

After abdominal surgery the gut can be slow to restart (postoperative ileus), and nausea and vomiting are common after anesthesia. These problems add to discomfort and are addressed together with pain.^{[7, 8]}

Acupuncture for Post-Surgical Pain

What the research shows

Acupuncture may reduce pain in the first days after surgery, but the evidence is mixed in quality and by type of surgery. A meta-analysis of randomized trials found less pain and less opioid use on the first day after surgery with acupuncture or related techniques than with control. Conventional acupuncture and acupoint electrical stimulation reduced pain, while electroacupuncture alone was similar to control. Only the electrical acupoint stimulation (without needles) reduced opioid use.^[9]

Procedure-specific reviews give similar, cautious results. After back surgery, a review of five trials found encouraging but limited evidence, with lower pain 24 hours after surgery than with sham acupuncture but no clear effect on opioid demand.^[10] After total knee replacement, a meta-analysis of seven studies with 891 participants found reduced pain.^[11] A network meta-analysis of 28 trials, mostly in China and Taiwan, found electroacupuncture was the preferred therapy for pain after knee arthroplasty, with no serious adverse events.^[12] Another review rated the evidence that acupuncture delays opioid use as moderate certainty and the evidence for pain improvement as low certainty.^[13]

After thoracotomy, a meta-analysis of 11 trials found lower pain scores and opioid use with electroacupuncture, but the authors noted low quality and high heterogeneity.^[14]

Not every trial is positive. In a sham-controlled trial of 72 women after gynecological abdominal surgery, pain was lower at one time point only, and the authors called the efficacy inconclusive.^[15] A meta-analysis of electroacupuncture and related stimulation found faster return of bowel function after abdominal surgery but no reduction in pain medicine use.^[7]

Stimulating the P6 point on the wrist reduced nausea and vomiting after surgery in a Cochrane review of 59 trials, with low-quality evidence against sham and no difference from antinausea drugs.^[8]

How acupuncture may work

Laboratory research suggests acupuncture, particularly electroacupuncture, may act on the spinal cord and brain. Proposed effects include quieting glial cells that amplify pain, lowering inflammatory molecules, and activating the body's descending pain-control pathways, which involve endogenous opioids and other transmitters.^[5] These are proposed explanations from mostly animal and laboratory work, not settled facts in people.

What treatment involves

Treatment uses fine, sterile, single-use needles, usually left in place for about 20 to 40 minutes, with a short course of visits and reassessment. Needles are placed away from fresh incisions, wounds and areas of infection, and treatment should begin only when your surgeon agrees it is appropriate. In one trial, acupuncture started before surgery and continued daily afterward, which is a hospital-based approach.^[15]

In prospective studies, about 9 in 100 patients had a minor reaction such as bleeding, soreness or redness at a needle site, and serious events occurred in about 1 in 10,000 patients.^[16] Tell the practitioner first if you have a bleeding disorder, take blood thinners, are pregnant, have a pacemaker or other implanted device (relevant to electroacupuncture), or have lymphedema or an implant near the area.

Ayurvedic medicine for Post-Surgical Pain

The Ayurvedic view

Ayurveda has a long tradition of surgery (Shalya Tantra) and describes pain after surgery as aggravated Vata, the principle said to govern movement and sensation, sometimes with local inflammation described as Pitta. These are traditional categories for choosing care, not biomedical diagnoses.

Therapies that may be used

Care is chosen for the individual and, after the wound has healed and your surgeon agrees, may include:

• Diet and daily routine meant to support recovery, such as warm, easily digested meals and regular sleep
• Gentle warm oil massage away from the incision once it is closed and healed
• Herbs used traditionally for pain and inflammation, such as turmeric and Boswellia, prescribed individually; Ayurvedic products vary in quality, and about one fifth of those bought online contained detectable lead, mercury or arsenic^[17]

Panchakarma procedures are not appropriate in the early period after surgery, during acute illness or frailty, or in pregnancy. Herbal preparations applied to the skin (transdermal medication therapy) are not used on a healing wound.

What the research shows

We found no clinical trials of Ayurvedic treatment for post-surgical pain. The evidence is none, and any benefit is unproven. The closest evidence is a placebo-controlled trial of a supplement containing Boswellia serrata and Curcuma longa in people having arthroscopic rotator cuff repair, which is described in the herbal section below.^[18]

Herbal medicine for Post-Surgical Pain

Herbs and formulas that have been studied

Research on herbs for pain after surgery is sparse. A supplement combining Boswellia serrata (Indian frankincense) and Curcuma longa (turmeric) has been tested in rotator cuff repair.^[18] For bowel recovery after surgery, Chinese herbal prescriptions have been studied within enhanced recovery programs.^[19]

What the research shows

The evidence is limited. In a placebo-controlled trial of patients having arthroscopic rotator cuff repair, those given the Boswellia and turmeric supplement before and after surgery had lower pain at one week. The difference was not significant at later time points.^[18] It was a single trial of one product, so it cannot be applied to other surgeries or products.

A 2026 scoping review of 99 studies found moderate-certainty benefit for electroacupuncture in restoring bowel function after gastrointestinal surgery, but only low-certainty evidence for oral herbal prescriptions and external therapies, limited by small studies and inadequate blinding.^[19]

Safety and herb-drug interactions

Herbs matter more around the time of surgery because some affect bleeding. Case reports describe bleeding events, including spontaneous postoperative bleeding, when warfarin was combined with herbs such as dan shen, dang gui, ginger, ginseng and Boswellia.^[20] Tell your surgeon and us about every herb and supplement before and after surgery, and do not start any herb without your surgical team knowing.

In one study, about one fifth of Ayurvedic medicines bought online contained detectable lead, mercury or arsenic.^[17] Herbs should come from tested sources and be prescribed individually. Tell us if you are pregnant or breastfeeding, or have liver or kidney disease.

Translating traditional medicine into modern biological language

The links drawn here are interpretation, not equivalence. Chinese medicine may describe pain after surgery as qi and blood stagnation at the injured site, with a depleted constitution slowing recovery. Researchers measure things that loosely parallel this picture: local inflammation, pain signaling in the spinal cord and brain, and the body's own pain-control pathways.^[5]

Ayurveda's aggravated Vata describes sharp, mobile or nerve-type pain. No study has shown that a dosha corresponds to a specific biological process.

How this care fits with your medical care

Care at our clinic is complementary and follows, not replaces, your surgical team's plan. Keep every follow-up, keep taking prescribed pain medicine as directed, and do not stop or change prescribed treatment on your own. We do not manage your wound or your surgical recovery, so questions about the incision or activity limits go to your surgeon.

Please bring your operative or discharge report, your medication and supplement list, and your surgeon's instructions. We ask that you are under a surgeon's or physician's care for this pain and that your treating team knows you are receiving complementary care.

When to seek urgent medical care

Some changes after surgery can mean infection, bleeding, a blood clot or another complication that needs prompt medical attention.

• Redness, warmth, swelling, pus or a foul smell at the incision, or fever
• Pain that is sudden, severe or rapidly getting worse
• A swollen, tender or warm calf or leg
• Opening of the wound or heavy bleeding
• Nausea or vomiting that will not stop, or a swollen belly with no passing of gas or stool
• New numbness or weakness, or a limb that turns cold, pale or blue

Call 911 or go to the nearest emergency department for chest pain, trouble breathing, fainting, or confusion.
