Suggest Cure For Sore And Swollen Knees With Ever Increasing Stomach Problems

Yes I am a 35 yr old woman usually reasonably healthy. I had a merina coil fitted a yr ago and I will say it has dramatically helped with heavy bleeding I was experiencing and now have only light spotting once a month which is great. Although over this last year I have been experiencing sore knees and swollen knees and ever increasing stomach problems. The last few months I have been backwards and forwards to different GP s all seem to think it s something different from inflammation of the stomach lining, dyspepsia and this last week now IBS. I am taking now two different tablets 1 in the morning before eating omeprazole then 3 times a day before food mebeverine. And although initially seemed to help combined with removing wheat from my diet for a few days. But I m just nit feeling right and my stomach becomes distended and rock hard at times but then not others after eating I wake in the night with upper abdominal/stomach pain. I get headaches and am tired all the time and I feel very much like the GP isn t listening or doesn t care as no other tests apart from a breath test for h pylori which came back negative. I find myself trying to find out myself here online what might be wrong coz it s really getting me down and effecting my whole life as we can t eat out we can t have friends round as I m eating hardly anything incase it upsets me, my life is on hold! Could this be anything to do with my merina coil?? Any help or advice would be great I m at my wits end and want to get on with my life I am getting married in May and if I Just don t want to feel like this anymore. Pjlong
