Hand Numbness/shoulder pain

[Zx1]

My father has been having right shoulder pain and right hand tingling/numbness. Its constantly waking him up in the middle of the night because he shoulder will start hurting and his hand go numb. He was saying that a friend of his had the same problems but it was from lacquer thinner poisoning. Im just wondering if maybe there is another  problem or not.His left arm is just fine. Im wondering if its a pinched nerve, a bad disk or what.  Maybe someone could give some options

Thank you caregiver222. Can pinched nerves be fixed fairly easy?

Hello,

I was having the numbness and tingling while taking hydrochlorothiazide.  I would stop taking it and the numbness/tingle would go away, take it again, and it would come right back.  Not sure if he is taking hydrochlorothiazide.  They had me on it for edema.  I have swelling in my hands and ankles, all tests neg except for CMV.  Battling this since April 2008. Hands so swollen, can't open bottles, hold a pen, hold a phone or peel the label off the top of yogurts..ect..

Yeah. It's a pinched nerve in the cervical area. No, it is not "laquer thinner poisoning". The option is to see a physician.
