Over the last couple of weeks I've noticed an aching sensation in my right shoulder,sometimes running down into my arm,and numb fingers on my right hand.The numbness in the hand is noticeably worse in the thumb and forefinger.I've had less severe numbness in my left hand before,and was told it was due to a shoulder allignment. There was no ache in the left shoulder,however,and the numb finger issue was alleviated by some stretches and push ups over about 2-3 weeks.I'm aware that I'm pretty lax re working opposing muscle groups,so I've probably only got myself to blame.Anyone have any ideas what this problem may be,or have any suggestions exercise-wise? Or is it physio time? All advice very greatfully recieved.
