When the Chest Still Hurts After a Mastectomy — How Surgical-Site Pain Eases and How to Help Your Shoulder and Arm Recover

Feeling aching, tightness, or a burning sensation at the surgical site for a while after a mastectomy is common. Surgery passes through not only skin and fat but also the fascia beneath and small nerve branches, so even after the outer wound heals, the deeper tissue and nerves take longer to recover. For that reason, pain that lingers around 10 days after surgery is often a normal part of healing rather than a sign that something is wrong.

In general, sharp pain at the incision is most noticeable in the first one to two weeks and then gradually dulls over the following weeks into a softer pulling or tightness. However, tingling or shooting sensations spreading into the chest wall, armpit, and inner arm can come and go for several months as nerves regrow. The pace of recovery varies from person to person depending on how much tissue was removed, whether lymph nodes were taken, and individual fitness and pain sensitivity.

Many people notice that pain worsens when raising the arm, changing clothes, coughing, or shifting position, because the chest and shoulder muscles are pulled together. If fear of pain leads someone to keep the arm tucked and unused, the shoulder can stiffen and lose range of motion (similar to frozen shoulder). Within the limits your care team allows, gently moving the fingers, wrist, and elbow and doing light stretches such as slowly walking the hand up a wall can support recovery. Taking prescribed pain medication before exercising often makes movement much easier.

That said, if pain that was improving suddenly worsens, if the site becomes increasingly red, warm, or leaks fluid or pus, if a fever develops, or if the arm swells noticeably (possible lymphedema), these may differ from ordinary healing pain and should be reported to your care team without delay.
