tingling in right hand about every 30 mins on and off 9 days

I have had tingling in my right hand, including all fingers except pinky and my palm. I have had it for about 9 days, it occurs about every 30 min on and off and lasts about 1-5 minutes at a time and them slowly goes away. I can feel a tightness (trigger pints ) in my upper back and shoulder and was wondering if it was a pinched nerve. I have been to the chiro and he adjusted me and did some kind of massage thing to the nerve in my arm. I do not feel any different.does anyone have any advice?
