Hi, I just finished my second treatment for H. Pylori. The first one didn t work, and I was put on a second treatment for 10 days. It wasn t until the seventh day where I noticed this tightness in my stomach and sort of in my back area. After I got off the treatment, the back pain went away, but my stomach has this tightness and very minor, faint pain. I noticed my left arm feels a little weird, too. Is this normal after doing treatment? I haven t been retested for H Pylori yet since I have to wait for two weeks after the treatment. Thank you for your time.
