Hello I ve. Had a absence. The size of an eeg once under my armpit when i was a teenager. It has came back and is not as big and painful. When i sleep it oozes and smells bad. I had decided. To squeeze it, and lo and behold something came out looking like brown wormy smelly stuff it was dry not wet looked as if it could have been old puss. It looked and smelled like Defecation. Im 50 now. I put it in a bag to save for my doctor. I also took pictures of it. What is it? ,do I need to get it checked? It s not painful at all.
