During the Easter weekend, I had a heavy fall directly landing on the shoulders (falling backwards) with my entire weight..... At the time it didnt really bother me, as it was during a childs party and so I didnt feel much at the time. However, its now been 2 months and I am suffering with pain in the area mentioned, it can be panful to breath and or to move.... some days its worse the others, however, sometimes it seems to effect my neck and even causing stiffness . Should I be concerned?
