My left arm pit hurts during daily activities. If I am sitting on the couch, doing nothing I feel a slight burn. When I walk or move (armpit movement), it hurts. I feel around and I do not feel any lumps or bumps. There is a growth there of a little pocket of fat, but my dermatologist said it was fine. It's been a few months and I keep complaining. I am a male, but did a mammogram and ultrasound. There was nothing found. EKG came back "perfect" according to the doctor. My heart xray came back, and the dotor said everything looked fine. My heart was slightly enlarged, but not to worry about it. My blood pressure is great. I am over weight, but cholesterol, sugar, hepatitis, and full blood work up was good. Today, again after months of pain, I put my right fingers and pressed into (not very hard but a lite push) into the middle of my left armpit. It hurt. I felt around again, but felt no bumps or lumps. I do have sever back right shoulder blade, right shoulder, and arm pain. However, the armpit pain is a different kind of pain. What's going on?
