It was suggested at the ms forum that I try this site. I have ms and arthritis. I was recently prescribed voltaren gel to use on my knees as I have had a problem with other nsaids causing stomach issues. I am relunctant to use this as I have a past history (about 10 years ago) of ulcers and I take nexium daily for GERD. I used it once on Thursday and became mildly nauseated about 6 hours later. MY pcp said that it should not be caused by the gel. I am supposed to use it 4x per day, but I only used it once yesterday as I an still experiencing nausea. She said I probably have a stomach virus that is going around. I think I am going to stop using it, and once the nausea has completely disappeared I will wait a few days and then try it again.
