MY RIGHT. ARM FEELS NUMB FROM MY HAND ALL THE WAY UP TO MY SHOULDER. THE NUMBNESS IS PAINFUL AT TIMES. THE PAIN IS NOT CONSTENT MAYBE ABOUT EVER 20 MINUTES AND LAST ANYWHERES FROM A MIN TO TEN MINUTES. I HAVE HAD THIS SENSATION FOR A FEW YEARS BUT HAS BECOME INCREASINGLY PAINFUL THE LAST COUPLE OF MONTHS. ANY ADVISE WOULD BE GREATLY APPRECIATED.
THANK YOU
