I do believe they made me gain weight but it could also have been the lack of physical activity due to the op. Although the benefits far out weighed the gain. I did stop them after a few months and the burning returned slightly but nothing in comparison and soon subsided. Now I am pain and pill free. They can be quite expensive especially if you don't have private health cover. My lovely GP would give me the samples she would get from sales reps so I only ever paid for them once. My surgeon also said gently massaging the area can help with the healing and burning sensation. All the best Lara xx
