so im injured as you read. mhmm...not sure where it is exactly except it feels like its in my armpit area. no clue. sore when i use my backhand or anything over the head .....its not actually sore..but maybe swollen..? or no clue lol....anyone ever experience anything like this? share your thoughts.
There are lymph-node clusters under each arm and they can become swollen and tender if you are sick with something. Do you feel sick or "under the weather" at all? It could be a simple muscle sprain or perhaps you are catching something. Either way, I would suggest seeing a doctor. Hope you feel better.
Dont ignore this pain , I had the same problem and in a week it became so painful that it was hard to lift my arm. I went to accupuncturist to get it fixed, she told me it was muscle fatigue which caused internal swelling... Take rest and go to a doctor.
