OK, the armpit isn't bothering me as much anymore...BUT my arm bicep and shoulder (on the top) are BURNING with pain and aching...and the part of skin from the armpit to the shoulder causes the pain if touched, etc...I'm starting to freak out, again....I want to communicate this pain to my doctor correctly without sounding crazy...I'm worried that I have loomig cancer somehow & it's making me feel horrible & scared. I'm trying to cover feeling depressed for my family & friends but that also makes me feel so tired and stressed....does this sound muscular? Bursitis? Tendonitis?
