Is This Normal? · After Surgery
The short answer on numbness after breast surgery
Yes, this is very common. Breast and lymph node surgery cut small nerves that carry feeling from the skin, and nerves heal more slowly than anything else in the body. Memorial Sloan Kettering says the strange sensations often ease in the first few months, though some last for years. Some numbness may never fully go away. Pain that keeps going past about three months is different. It has a name, post-mastectomy pain syndrome, and it can be treated.
What to know about numbness after breast surgery
- It's the nerves. Surgery on the breast or armpit cuts small skin nerves, which leaves patches that feel numb, tingly, tight or odd.
- The armpit and upper arm count. A nerve that runs through the armpit to the inner upper arm is often affected by lymph node surgery.
- Feeling a breast that isn't there is real. Phantom breast sensations are common after mastectomy and are not "in your head."
- Lasting pain is treatable. Medicines, physical therapy and other options can help, so it's worth bringing up.
- Numb skin can't warn you. Keep heating pads, hot water bottles and ice packs off areas you can't fully feel.
Why does your chest feel numb or strange after breast surgery?
The nerves that give feeling to the skin of the breast and nipple run through the breast tissue. Remove the tissue and many of those nerves are cut.
If you had lymph nodes removed from your armpit, there's another player: the intercostobrachial nerve. It comes out between the ribs, crosses the armpit and supplies feeling to the inner upper arm. It sits right where surgeons work, and its branching varies a lot from person to person, so it's hard to protect every time.
A 2024 review found surgeons fully preserved this nerve about 63 percent of the time during armpit lymph node surgery. Even saving it isn't a guarantee: in one study, 20 percent of women whose nerve was kept still had numbness or tingling six months later.
Memorial Sloan Kettering says cut nerves can cause tenderness, numbness and twinges, and even the feeling of liquid running down your arm when nothing is there. It's a nerve signal, not a leak.
How long does numbness after breast surgery last?
There isn't one timeline. Memorial Sloan Kettering says these sensations usually come and go, often improve within a few months, and can sometimes last five years or longer. Most people don't find them severe.
An NHS breast surgery leaflet from Royal Devon says armpit and upper-arm numbness tends to improve but may not go away completely, and that it doesn't affect how you use your arm. So a patch that's still numb a year out can be normal. What matters more is whether it hurts or gets in the way of your life.
Why can you still feel a breast that has been removed?
Breastcancer.org explains it this way: the nerves were cut, but the brain keeps sending signals as if the breast were still there, much like phantom limb feelings after an amputation. People describe itching, pins and needles, pressure, burning or throbbing where the breast used to be, and sometimes a sense that the nipple is still there.
How common it is depends on the study. A review in the Indian Journal of Palliative Care put it anywhere from about 30 to 80 percent of people after mastectomy, and noted it can sometimes begin more than a year after surgery. Breastcancer.org says having breast pain before surgery makes phantom pain more likely.
When does pain after breast surgery become post-mastectomy pain syndrome?
Post-mastectomy pain syndrome, often shortened to PMPS, is ongoing nerve pain in the chest wall, armpit, shoulder or upper arm after breast surgery. Despite the name, the American Cancer Society says it can follow lumpectomy, too.
It can feel like burning, shooting or pricking pain, tenderness at the scar, or intense itching. Three months is a common line, but experts don't fully agree; a 2024 review in Cureus says three to six months is generally accepted.
How common is it? The numbers are all over the place, and it's worth being honest about that. The same Cureus review cites 36 to 47 percent of people with pain beyond three months, and 28 percent in the largest study it describes. A 2021 review in JPRAS Open gives a range of 25 to 60 percent. A 2023 study that followed women from before surgery found about 15 percent had moderate to severe pain six months or more afterward. Studies define and measure pain differently.
Who's more likely to get it. The American Cancer Society names younger women who had a full lymph node removal rather than a sentinel node biopsy, women who had radiation after surgery, women with excess body weight, and women living with anxiety or depression. It also says PMPS is less common than it used to be, because full lymph node removal is done less often now.
What helps numbness and nerve pain after breast surgery?
There's no single proven first treatment for PMPS, and many studies are small. These are the options sources describe.
Nerve pain medicines. The American Cancer Society mentions gabapentin and venlafaxine. Reviews also describe pregabalin and amitriptyline, an older antidepressant. They work differently from regular pain relievers and can have side effects. Take them only as prescribed.
Skin treatments. Capsaicin, the compound that makes chili peppers hot, has helped some people as a cream or patch in small studies, according to the Cureus and JPRAS Open reviews.
Physical therapy and exercise. A 2022 review of 18 trials found that exercise improved both pain and quality of life for women with PMPS. Once the wound is fully healed, the Royal Devon leaflet suggests massaging the scar with an unscented moisturizer to soften it.
Desensitization. If light touch has started to hurt, therapists may teach you to retrain the skin by stroking it with soft, then rougher, textures, a little every day. Most written guides are for hands, so ask a physical therapist how to adapt it.
Procedures and more. For stubborn pain, specialists may offer nerve blocks, injections into a tender spot on the scar, or treatments that use heat or electrical signals to quiet a nerve; the evidence is promising but limited. The American Cancer Society also lists guided imagery and music therapy.
Does feeling come back after breast reconstruction or nipple-sparing mastectomy?
Reconstruction rebuilds the shape of a breast, but it doesn't automatically bring feeling back. The American Cancer Society says some types don't restore normal feeling, though some sensation may return over time.
With flap reconstruction, which uses your own tissue, a 2024 Stanford review found most flaps got back some feeling within a year, while some stayed numb for years. Connecting a nerve in the flap to a nerve in the chest tends to bring feeling back sooner and more fully, the review says. If sensation matters to you, ask about it before surgery.
A nipple-sparing mastectomy keeps the nipple, but not necessarily its feeling. The American Cancer Society says there's a good chance you'll have less or no feeling in the nipple, because the nerves are still cut.
How do you protect numb skin after breast surgery?
Skin that can't sense heat or pain can't warn you. The Stanford review points to a series of medical reports of burns on numb reconstructed breasts. Memorial Sloan Kettering advises against putting anything hot or cold, like hot water bottles, heating pads or ice packs, directly on the surgical area. Breastcancer.org suggests avoiding very hot water on numb skin and treating cuts and scrapes right away.
