A skin infection in your armpit can cause burning pain as can an allergy to a new product that you are using. Burning pain can be the result of deodorants or antiperspirants that your skin can not tolerate. If you are taking an oral medication that disagrees with you, it can result in burning pain in your skin, including in your armpit.
Conditions that can result in a burning sensation in your armpit include peripheral artery disease or PAD; peripheral neuropathy; diabetes; a sun burn; an injury to your underarm; or a brachial plexus injury, which means you have damaged the network of nerves that transfers signals from the spine to the arm, hand and shoulder. The burning sensation, along with a pins and needles sensation, tingling and partial numbness, is called paresthesia. This can be caused by nerve damage or disease.
A lump in your armpit that is swollen and painful can be the result of a skin infection. If the lump has been caused by infection, it will eventually drain; however, you may need to take an antibiotic. If the lump persists and doesn’t appear to be the result of an infection, have it checked by your physician, recommends Dr. Hannah Brooks.
When experiencing armpit pain, the most common reason is swelling of the lymphatic glands due to a virus. Armpit pain can also be the sign of cancer. If your pain is caused by swollen glands, it will disappear within a few days. If it doesn’t go away, have this examined by your doctor, Armpitpain.net recommends.
Burning armpit pain can occur if you have shaved too closely. If you are wearing clothing that is too tight in the armhole area and which is repeatedly rubbing against the armpit area, it can cause pain.
Shingles, a variation of chickenpox, commonly cause armpit pain. With shingles, small blisters develop that affect nerves.
