What Causes Tingling Sensation And Numbness On The Right Hand?

I have diabetes type 2 my right hand particularly is bothering me it doesn t function properly yet I manage to do my tasks, it lacking feeling, tingling, numbness, getting more pain a little bit. All my life I exercise quite a lot. Lately I haven t been working out. I was thinking going to where I go for a massage maybe she could phone someone for advice in case she is nervous or unsure. I plan to try to work out again, dance, sports, brisk walking, etc. I am 61 years of age & need to lose weight.
