Have you done any strenuous work or lifting recently?

Have you been recently ill?  i.e. cold, upper respiratory infection

i have been experiancing the same thing but my pain is travelling around to my lower belly,i put it down to my IBS,but it is freaking me out as someone said it could be a gallstone

I have been experiencing the same pain for over a year now and all the doctors tell me is that it is a strained muscle but it should not still be hurting. I hope you get better soon because this pain has changed my lifestyle, I am unable to do the things i use to do. Does your pain get worse after standing for a long period of time?
