I am a 40yr-old Female, non-smoker 5'2 112 lbs. Avid exerciser(6xweek)I have been a vegetarian for 1 1/2 years although I do eat salmon & halibut 1-2 x a week. Hysterectomy & bladder repair 2001(due to large fibroid), abdominalplasty 2004.I Take 25mg Hydrochlorothiazde for Hypertension that medical tests & imaging could find no apparent cause for(began meds in 6/2004) I am adopted and have no medical history. One month ago had increased need to urinate w/low back pain. Subsided after 2weeks. Then I began to have lower & mid back pain with tenderness in abdomen around naval. This comes and goes.I also began to have lateral upperabdominal burning which radiates to my back.This occurs mostly when sitting down .(this is not helped by pepto, tums or zantac) For past 3 days the burning is now also on upper right side and up/down my right arm.(I have had this type of burning in the past, but did not seek medical treatment.) The naval area& mid back is also still a little tender and I have some abdominal bloating. I have had episodes of crampy pain and diarrhea in the past, but this has not occured for at least one year.For the past 3 days my stool has white stringly mucuous in it as well as some undigested food. I have no diarrhea, vomiting, weight loss or nausea. I have become more constipated over the past few months but metamucil fixes this problem. My doctor ordered an abdominal ultrasound but says he has no idea what's going on. Do you have any ideas on what types of tests I should be having and what types of conditions my symptoms may suggest?
