I have been taking anti-inflammatory (Mobic) for about 2 years now and I have gained 30# even with exercising 4-5 times a week and dieting. I need to take them for my knees, but the excess weight is hurting me more than ever. I spoke to my doctor, but he changed my script to Voltaren, which is another anti-inflammatory and I am afraid to take it for fear of gaining even more weight. Does anyone have any suggestions?
