To answer your questions
1. Lessening of burning symptoms-- it did not help me
2. Little to no weight gain-- gained over 30 lbs
3. No swelling-- legs and ankles wear very swollen.

It seemed very time I told the doc it did not help they increased the dose. I have been off it for a month lost 25lbs and the swelling is gone. I’m on new meds now and they are really helping me.
