I Have a Question

what does it mean if your arm has been sore for months? ive told my doctor about it a couple of times, last time i saw him he ordered xrays, i had to wait till they trained someone to do them, i went last wk and yesterday the clinic calls me and says my doctor wanted to see me, so now im seeing him next wk, i dont think its heart related or i wouldve had a heart attack by now, i do have excema issues in my arm and wondered if i could have an infection, ive wondered if it could be neurological cause sometimes i forget stuff like people's names when ive known them for yrs,stuff like that, things like brain tumors and alzheimers have happened in my family, i do have arthritis issues too, my arm did look a little swollen, ive wondered if it wasnt some kind of tumor or if my doctor just wanted to do more testing , this is the first time theyve called me to come in for an appt like that, any idea of whats going on? i did ask this on healthtap.com too, but i just wanted others opinions too
