What causes tingling in right hand and arm?
Patient: Often when I am sleeping or first wake up, I get a tingling in my right arm and hand. This has only started occurring less than 4 weeks ago. What might be causing it, and how can it be stopped? I am sorry to have wasted your time. I thought it was free to ask the question or that I would be directed to a webpage where I might read about things like this. Doctor: hiYou are welcome to seek help.The symptoms are probably due to neuro-vascular impingement i neck or axilla or  elbow.frquently faulty postures like lying on shoulder with arm under the body may give pressure to nerves or blood supply temporarily cutting off - or there may be cervical spondylosis, cervical rib,shoulder outlet syndrome which can be ruled out by x ray and consultation/examination by an orthopedic surgeonIn medical conditions, Vitamin B6,B12 deficiency,diabetic neuropathy are common causes which can be ruled out by blood levels testsRegards
