I have been having pains in my right arm for sometimes, now it radiates to my fingers and my right leg. what is the possible cause and solutions?

Nerve impingement: Of the neck or lower back is a very common problem, affecting about 10-12% percent of the adult population in the us. Nerve impingement can be caused by being sandwiched between two spinal bones, pressed by a bulging disc or encroached upon by bony overgrowth. It can cause severe vision impairment and muscle spasms. Rec.: see an interventional pain management specialist for further investigation.
