What kind of doctor should I see for my arm?

Question

my arm really hurts when i lift it (possibly due to the nerves)
what kind of doc should i see?

Answer 1

Start with your primary care doc. It could be a number of things. You didn't list any age or activities so it is impossible to make a diagnosis but several guesses would include:
Rotator Cuf Injury
Artharitus
Pulled Muscle

Your PC can make a better guess with more info and send you to a specialist if needed.pp
