Probably been asked many times and I have searched online a lot. I have a pain like broken shards of glass combined with sandpaper and bruising. It's kind of a feeling like I have a burn injury Its about the size of my palm. I have been searching anything I can find about what causes this, I have been to the doctors, I have no lump. Started about 5 months ago. I have a referral on the two week pathway to get checked and will come and update this afterwards in case anyone else searches in the future. It has developed over the last 5 months and started with a pain in my arm pit and I thought I was being heavy handed with deodorant and causing bruising. I thought I have been over heating at night and even got up and applied Sudocream! Also stupidly I thought I had an ingrowing hair as all the hairs are extra sensitive in the arm pit itself and let my hair grow to see if that helped. Also ridiculously I only looked under my arm in the mirror this weekend which is why I saw there was nothing there and it must be another issue. I feel daft for never looking earlier but I am fighting through the courts to fully escape a domestic abuse situation and working more than full time to avoid mounting debts from the court process as much as i can. Has anyone had pain like this and what did it turn out to be? Can you have even cancer and no lump?
