I too am taking Nexium Hp7 plus Levofoxacin, a totally of 5tablets x twice a day for helicobacter pyroli. I am also taking probiotics. I have a very sore, red mouth and tongue, a terrible metallic taste and am always thirsty. By allowing an hour before or after food I have controlled the nauseous stomach. By day 4 I noticed sore muscles and as this was worsening by day 6 I rang my Dr who organised blood tests. Tests came back clear but Dr requested I continue if I could. It has been quiet a battle as muscle pain and restlessness, especially in my groin and legs has continued to the point that I have trouble sleeping, getting out of a chair, and hobble around through the day. Thankfully today is day 14 as I ve had enough. Has anyone had similar problems and how long does it take for the muscle pain to go.
