@yashwant Hello, Possible causes include hernias, lipomas, hematomas, undescended testicles, and tumors. You should definitely see the doctor as you have pain. A person with an abdominal lump that is causing severe pain or that coincides with fever, vomiting, or discoloration should seek immediate medical attention.

Hello, I am 17 years old male and I have had this lump in my armpit that keeps going away and growing back bigger. It’s been going since October. It doesn’t hurt but it is getting bigger. Could this be serious? What causes lumps under the skin of arms?
