Pain After an Operation

What normal pain after surgery feels like

Surgery injures skin, muscle and other tissue, which releases chemicals that sensitize nearby nerves. Expect:

• Aching or sharp pain at the incision, worse when you move, cough or laugh
• Pain that peaks over the first 1 to 3 days and then eases
• Bruising and mild swelling around the wound
• Numbness or tingling near the scar as small skin nerves were cut; this can last months
• Pulling or itching as the wound heals

Pain that has another source

• Shoulder-tip pain after laparoscopic (keyhole) surgery comes from gas used to inflate the belly irritating the diaphragm. It settles in 1 to 3 days. Walking helps.
• Sore throat from the breathing tube lasts 1 to 2 days.
• Back and neck aches from lying on the operating table.
• Gas pains and constipation from anesthesia, opioids and reduced movement.
• Headache after spinal anesthesia, worse when sitting up, needs a call to the hospital if severe.
• Muscle aches from a muscle relaxant drug used during anesthesia.

How long does pain last after surgery?

Older age, anxiety about pain, poor pain control early on, and pain before surgery tend to make recovery more uncomfortable.

Managing pain after an operation

Medicine plan

Most hospitals use a multimodal approach, combining medicines that work in different ways so each can be used at a lower dose:

1. Acetaminophen (paracetamol): the foundation. Take it regularly, at the label or prescribed dose, rather than waiting for pain to build. Check other products for hidden acetaminophen.
2. NSAIDs such as ibuprofen or naproxen, if your surgeon agrees. They are avoided in kidney disease, stomach ulcers, some heart conditions and after certain operations.
3. Opioids (such as oxycodone or hydrocodone) for severe pain, for the shortest time, usually only a few days. They cause drowsiness, nausea, constipation and slowed breathing, and carry a risk of dependence. Never combine them with alcohol, sleeping pills or benzodiazepines, and do not drive while taking them.
4. Nerve blocks and local anesthetic given during surgery can numb the area for 12 to 24 hours or more. Take your oral medicines before the block wears off.

Store opioids securely and dispose of leftovers at a pharmacy take-back site.

Non-drug measures

• Ice packs (wrapped) for 15 to 20 minutes at a time after orthopedic surgery, if approved
• Support the wound with a pillow when you cough or sit up
• Short, frequent walks to reduce stiffness, gas pain and clot risk
• Elevation to reduce swelling in limbs
• Sleep, relaxation breathing and distraction
• Stool softeners or laxatives while you take opioids

When to worry about pain after surgery

Pain that does not follow the normal pattern of slow improvement is the main warning sign. Causes to rule out include:

• Wound infection: see postoperative infection. Redness spreading from the wound, warmth, pus and fever, usually 3 to 7 days after surgery.
• Blood clots: deep vein thrombosis causes calf pain and swelling. A clot that travels to the lungs, a pulmonary embolism, causes chest pain and breathlessness.
• Bleeding or hematoma: a swelling, tense, bruised wound.
• Anastomotic leak or bowel problems after gut surgery: worsening belly pain, fever and vomiting.
• Compartment syndrome after limb surgery or fractures.
• Heart attack in older adults or people with heart disease.

Chronic pain after surgery

In some people, pain continues for more than 3 months after the wound has healed. This chronic postsurgical pain is most common after amputation, breast and chest surgery, hernia repair and knee replacement. It often feels burning, shooting or electric, a sign of nerve injury. Early recognition matters. Treatment may include nerve pain medicines, physical therapy, nerve blocks and psychological pain programs. Rarely, complex regional pain syndrome develops, with burning pain, swelling and skin changes in a limb.

Frequently asked questions

Is it normal to have pain after surgery?

Yes. Pain at the wound site is expected and usually worst in the first 1 to 3 days, then gradually improves. What is not normal is pain that is getting worse, pain with fever or a red, leaking wound, or new chest, calf or severe belly pain.

How long does pain last after surgery?

For minor and keyhole operations, most pain settles within 1 to 2 weeks. After major open or joint surgery, pain often lasts 4 to 6 weeks or longer, with a steady downward trend. Pain lasting beyond 3 months is called chronic postsurgical pain and should be assessed.

Why does my shoulder hurt after keyhole surgery?

During laparoscopy, carbon dioxide gas inflates the belly. Leftover gas irritates the diaphragm, and the nerve it shares sends pain to the shoulder tip. It usually fades within 1 to 3 days. Walking, warm drinks and pain relief help.

Why is pain sometimes worse a few days after surgery?

Long-acting anesthetic blocks wear off after a day or two, and you start moving more, so pain can rise briefly. A small rise around day 2 or 3 can be normal. Pain that keeps climbing after that, especially with fever or wound changes, suggests infection or another complication.

Should I take pain medicine regularly or only when it hurts?

In the first few days after surgery, taking acetaminophen and any NSAID on a regular schedule controls pain better than waiting until it is severe. Use opioids only for pain the other medicines do not cover, for as short a time as possible, and stop as soon as you can.
