tingling

I have experienced tingling in my upper right back near the shoulder blade for past few weeks thats intermittent and then the tingling has radiated to my right hand particulary the fingers.  I have notice no weakness in the hands.  Using tylenol and ibuprofen has had minimal affect.   The symptoms have subsided in the arms and fingers now but I have noticed tingling sensation in my left upper neck occausionally and also tingling in the feet, right foot and toes more than the left.  The sensation sees to be worse when more pressure is put on the foot for longer periods of time.  
       At first I think, I may have carpel tunnel but the neck and feet tingling confuses me.  What do you thing could be the cause of these problems and what treatment is recommended.

Thanks
