I have a lump under the skin, in my armpit. It gets bigger and smaller. It has been there for about 3 months. No redness, most of the time looks like a pea under the skin. Recently, I have begun to have sharp pain, on and off, in the left side of my breast. Same side as lump.
Hi, thanks for sharing your health concerns with Chat Doctor. Well, this is a common problem and not to worry at all about this! Actually the tissues worrying are nothing but ectopic breast tissue under your left maxilla that get cyclical changes under hormonal influence like normal breast tissue/glands! The tissue, that time, is congested and form some small cysts; return to normal when period is over... However, It could be a fibroadenoma or some lymph node also.therefore, not to worry about this and see your clinician for some tests like USG/FNAC for confirmation. Hope this answers your question. If you have additional questions or follow-up questions then please do not hesitate in writing to us. I will be happy to answer your questions. Wishing you good health.
