I have H. Pylori & am taking tettracyclin, metronidazole, omerprazole & peptones bis ol. I am experiencing so much pain & now, when I take my meds I get terrible headaches, ringing in my ears & increased stomach pain, sweating. Are these simply a result of taking these drugs? What can I take to help eliminate these additional symptoms? Please! I am already in so much pain. I had been complaining about the stomach pains since Oct. 2013. I think sometimes doctors may feel that old people are a bother. I am a 68 year old woman & Also, I am concerned that this bacteria may have spread to other organs. Is this possible?
