No I dont recall injuring that area. I lift my kids all the time with this arm. No a particular pistion doesnt really bother me. It just hurts all the time.
Hi.
It could be a sweat gland clogged. It will probably need to be drained, if it becomes painful. Do you recall having injured your underarm area?
Does any particular position or action make the pain worse or better?
Regards
It looks like a misquito bite really it is the size of a dime.
Hello.
Do you recall injuring your axilla? This appears to be a neuropathic pain. Neuropathy has the symptoms such as burning sensation, tingling and pain.
In your case, there is a nerve which is getting compressed. You will need to get EMG done for confirmation of a nerve compression.
How large is the skin swelling?
Regards
