Hi. I have had h pylori for a while I was prescribed the treatment of lansoprazole clarithromycine and amoxicillin ... I suffer from panic disorder. My type of panic attacks are from feeling different. I can't drink I can't take me da I can't feel different. A simple light headed Ness from a sinus infection makes me feel off and causes anxiety. I finally got a friend to come for the weekend so I can start treatment and within the hour I started to feel like it was a bit difficult to swallow but not effecting my breathing. Then my taste was like medicine and pasty... I then looked at my tongue and it was huge and swollen. I chose to not take the second dose. After reading in all the medications I feel like maybe the clarithromicyn is what is causing the side effects. If I'm allergic to it is there not her treatment or is there any natural treatments? I am tired of the pain and aches and swollen stomach. I eat different so it's contained but I don't want it leading to ulcers or worse ... stomach cancer. I'm terrified and it's giving me anxiety
