This isnt really related to back problems but I couldnt find a forum on shoulders so the nearest would be a back forum.

Mods help me move this thread if there is a shoulder forum. Thanks

onwards
my shoulder gets very sore after a few hours of wearing a sling back across my chest and slung on my right shoulder. This is the only shoulder that gets sore or aches after wearing a sling bag. The pain will last for an hour or two after wearing the sling. Thing, is, the pain gets more severe and lasts longer the more I wear my sling. What could be the cause? Is this normal? Ive tried not to wear a sling but on some occassions, it just seems appropriate to have a sling bag draped across your body. Im 18 and turning 19 this year. Could this turn out to be a major problem? Should I see a doctor? Or does everyone experience pain when wearing a sling bag?

Help would be greatl appreciated.
