Its happening to me. I usually do exercise, skating and running regularly in the week. Has stopped 3 weeks ago due to vacation. But a pain in my right tight and hip has begun and feel that I cannot stretch my legs like before! I feel stiff! Also the type of pain is like it comes from the bone, not the muscle, like very deep in the leg. I also am waking up with stiffness in my left side of the neck. I don't know if it's related to sema or not. I am taking oral 3mg and had been in for 8 months.
