Hello. I'm new here. For about the past 6 months I have had constipation, gas, and bloating along with some frequent urination. I went to the dr. last month and he checked my urine and blood and all was fine. He had me off all dairy for 2 weeks to rule out lactose intolerance. I was fine for the 1st week but the second week all my symptoms came back. He said if it is not lactose intolerance then it is probably IBS. I go back to see him in a couple of weeks. In the mean time I have noticed that sometimes I have a dull ache about where my kidneys are sometimes a little lower(usually on the right side but sometimes on the left) that moves around from my back to the front of me in about the same position sometimes a little lower (usually on the right side but sometimes on the left). I have also noticed that sometimes this goes away after I am able to have a BM, but not always. It also comes and goes. Sometimes I have this ache several times a day and sometimes I won't have it at all for several days in a row. I was just wondering if anyone else experiences this and if this could possibly be a side effect of IBS?Thanks!
