[|Human|] Hi, ive experience a lump in my arm pit 4 times in under a year. It hurts a lot, usually when stretching my arm or putting deodorant on. I usually stays for about a week then goes away. What can cause it? my doctor says its a swollen lymph node last time I had it around easter. But now its back again.
[|AI|]  Hi ! Good evening. I am Chat Doctor answering your query. From your history, it looks like a sebaceous cyst in your arm pit which gets infected secondarily with bacteria to give rise to signs of inflammation like pain, redness, etc. If I were your doctor, after confirming my diagnosis by a personal local clinical examination, I would refer you to a general surgeon for a possible excision biopsy for a confirmation of the diagnosis and a cure. Till then, you could go for an over the counter anti-inflammatory Chat Doctor. I hope this information would help you in discussing with your family physician/treating doctor in further management of your problem. Please do not hesitate to ask in case of any further doubts. Thanks for choosing Chat Doctor to clear doubts on your health problems. I wish you an early recovery. Chat Doctor.
