I've also had trouble getting below 10 mg. I've been on prednisone for a year now for PMR, starting at 15 mg and now stuck at 10. I saw my doctor yesterday and he told me to keep trying to taper -- starting by going from 10 down to 7.5, which to me would be *far* too steep of a drop. So I just kind of let that go in one ear and out the other. I'm going to try going down to 9.5, since the last time I went down a whole mg to 9, the pain returned. On the plus side, my most recent bloodwork was very good, except one of the inflammatory markers (can't remember which one) was still slightly elevated. My blood pressure was also okay. I think the improvement in those areas may be due to the dietary changes I've made over the past six months -- i.e. cutting red meat, drinking a lot more water, trying to eat more fruit and veggies, and really restricting my salt and sugar intake. Either way, taping down the prednisone seems to be a long, slow process, with quite a few hitches along the way. I've learned to listen to my body, rather than the doctor, when it comes to how fast or slow to taper.
