Hi doc, I m not sure what I have but its painful. My hands , wrist and elbows hurt , hands get numb so bad that it wakes me when I m asleep and I have to get up n shake it off and sometimes that don t work,I get cramp s in hands and it feels like needles are going threw them. My elbows hurt so bad that I have to wear tight elbow pads and if I have my arms straight for a few minutes it stiffens and hurts to bend and vise versa, and if I take off elbow pads for a while instant pain. Its been like this for 4 to 5 yrs I work in construction field for the last 10 yrs using all sorts of power and non power tools, jack hammers, compacting wackers etc. Ran heavy equipment, shoved and hammers etc... I ve been unemployed for 2 yrs but been working side jobs doing the same things and I have no insurance to find out what s wrong, do you have any ideas what can be wrong?
