I've been to the hospital a few times for what i thought were aches and pains. my doctor just gives me pain killers but it's not what i need. i got x rays on my joints, and they claim that nothing is wrong, maybe a sprained ankel for example but no big problems. my left arm has a burning pain from my neck down my shouler to my hand...and in training after boxing for awhile my arm feels super heavy. im tired of the pills and always being tired especially if it's just a lazy ass doctor not wanting to take me seriously. what could i review online to figure out what s going on or does anyone have any advice?
