I have a persistent aching in my left forearm. It hurts picking things up and reaching high up, into cupboards for example. The only information I can find on this is that it could be RSI. This astonishes me as I do not spend hours on a computer - I did work in the computer industry but this was over 10 years ago. I can not think of anything teaching related that could cause it. The only repetitive thing I do is board work and that is with my right hand (I am right handed). I do use a computer but not persistently, maybe 1 hour a day. Has anyone any ideas on what could be causing this? Who should I see to get advice? a doctor? Thanks in advance for any advice.
