Dimethyl Fumarate is supposed to reduce relapses. It won't reverse damage or symptoms if that's what you're expecting. Now if you are referring to flushing or other side effects of DMF, there is a way to really feel the difference of Tec. Head over to your nearest Trader Joe's and buy Trader Joe's Fiery Chicken Curry. A few hours later you might experience flushing of both your skin and household plumbing. That combo frequently turns me a bit purple, head to arms.

As above its not designed to help your existing symptoms. If you get flushing try Asprin alongside Tec and Omeprazole for GI soreness. Take with a spoonful of peanut butter.
