From the top 3/4 disc of the spine and from the center to the right where the spine ends and back shoulder muscle is connecting, at that point i feel the pain. While working in office if I dont set the chair at a high level and if i dont use hand rest for my right hand, I feel the pain. If I set the monitor at a lower level than my eye level, after working 5-6 hours I feel the pain. I do workout and basic shoulder exercises but even after 3-4 sets of push up I feel upper back muscle attached to that spine location is paining. I have given an image of the location of pain.
