I have fatty underarms. After the birth of my daughter in 2020 it seemed to have increased. I went for a check up on 2021 and doctor did sonography on my breasts and underarms and said it is normal post delivery. Recently my fatty underarms seems to have grown, and I keep on pressing my left underarm more to check lump, my underarm is soft and I can only feel the tissue. But I don't know I always feel disturbed of the excess fat and due to this constant checking of lumps in my underarms, today I am feeling some occasional pain while especially stretching or lifting heavy objects. is it something serious. Please guide
