Hi, I noticed tingling sensation and numbness in my right hand few minutes after I start writing with a pen. I am a grad student and use the computer to type a lot. I felt its because I don t use pen a lot like before. But over the past few weeks, It seems to be worsening...even when not typing like if I bear weight on the right hand or type I just have this pin and needle sensation. I had an hbaic over a week ago which is 5.6. Am not diabetic nor have any medical condition, not taking any medications. I am fine generally apart from being stressed by school . What do you think is wrong?
