When I had the flare up, I had many of the same symptoms you described. It always starts with my shoulders and neck hurting. then the hips get a weak feeling, like my legs don't want to hold me up. Then I get headaches. If I was you, I would go back to 10 and see what happens. You don't want the flare up to get worse. Dr. Zaidi told me to stay a couple of months at each level when I know I'm good go down by 1/2 mg. and repeat the process.
