For a little bit over the past month, I have been having many symptoms along with a odor that does not seem to go away no matter what I do. Over a month ago, I went to the doctor's office complaining that I have too much gas coming out of me throughout the day and that I feel some pressure/wetness in my rectal area at various parts of the day. I was told to take maalox, but this did not help. Then I was told to take prevacid 15mg, but stopped because my left arm was feeling strained along with the left part of my chest. Also, I was feeling itchy throughout my body, mostly around my legs. There was also a loss of appetite. Before beginning the prevacid, I noticed that I would have to go to the bathroom twice a day and would not feel completely empty sometimes. I went back to the doctor and was told to take metamucil, which still made me go twice a day to the bathroom, but after going once, I would notice some pain in my abdominal/stomach area and would have to go again. When this did not work, I was told to try Zantac 150 mg, which helped to decrease the stomach pain, but did not help with the pressure problem. I have visited an GI and have been told to take Levsid for 4 weeks. He said I may have IBS, but I don't think he's right. Right now, I still have an odor issue (which is really interfering with my life and I would do anything to get rid of it), still have to go 2 times to the bathroom (once, then 40 min later), still feeling pressure along rectal area, loss of appetite, white marks on hand nails. What could possibly be wrong with me? What should I do?
