Random Arm Pains in Teen

[SunshineMoon100]

My DD is 16, for a few days now she is complaining of arm pain, at first it was her right arm, I thought it was just overuse. Then she said the pain keeps
switching location, sometimes in her hand then lower arm then can present in her elbow. Since last night she says its radiating between both arms, I will call GP on Monday but in meantime wanted to see if anyone has experienced anything like
this.

I used to have something like this - occasionally sharp twinges switching between my right hand and elbow. It turned out to be RSI from typing (using a PC keyboard) at a funny angle.

Just to update. Dr has requested blood tests.
