s anything like that. I had the same symptoms years ago and was diagnosed with
tennis elbow, which is caused by overuse, not necessarily from playing tennis :) . It could also be a pinched nerve in your neck, causing pain to be referred down your arm. And as Tuck said, it could just be a strain.
I would try ibuprofen and resting the arm when possible. If it's nog better in a week or so, see a do tot if it's really bothering you. Good luck on your finals!
