Shoulder Pain

I was reading about apidexin a while ago when I felt this shoulder pain. I've been feeling this pain for quite sometime already and I think this is because of using and facing my computer everyday. The muscles below my neck on both sides are also aching. Although the pain is tolerable, still it destructs me especially if I need to finish something really important. As I am writing this post now, I can still feel the pain, lol. I think the pain knows that I am talking about him hahaha!
