I was on 20mg for 2 months and because that was working pretty well, my rheumatologist had me taper to 15. After 3 days, the pain increased so she told me to up it to 17.5. I was on that for a little over 2 weeks and 2 days ago went back down to 15. Pain has increased, but I am going to try and stick with the 15 for a full week and see how I am doing. It is easy for me to overdo exercising so I am sticking with swimming and pool yoga before I make a decision to go back down to 15 to make sure I am not doing too much. Walking is good and I do 20-25 minutes of various stretching in the morning so I am able to stand straight and walk.
