Hi, for the last 2 months now i have had pins and needles in my arm and fingers on my right side. Its worst when i tilt my head back and to the right and my neck area is very tender. Its also worst when i am seated. I think this problem which i have had on\off for 2 years is defo posture related as i seat all day at work. Has anyone had these symptoms and if so can you recommend any exercises to help?
