I had a car accident 4 months ago and forced my hand on steering wheel. I had whiplash, back and shoulder pain and went to a chiro from Nov2015 till Feb2016 then after two weeks left hand start swelling again (still working at the warehouse lifting 15-30lbs in a 40 degrees Temp) particularly on my knuckles three fingers from my pinky. I had xray and its negative did a lot of test for rheumatoid or gout and it's also negative. Having trouble lifting heavy stuff and weaker grip that cause some pain. I have numbness, tingling and shooting pain and feel some pain on my palm. I've been told by physical therapist/physician that they don't know what causing it but I still have to use personal leave from work since they won't allow me to do modified work. It's been bothering me a lot specially @ night having trouble sleeping at times. Taking some steroids 5mg tablet for a week (did that twice already last year and this year ) and some pain reliever. Just don't know what's goin on when doctors says they don't even know either. Need your help. Thanks!
