I started Mirapex about a week ago for restless leg syndrome. That is what my doctor thought my pain in the back of my knee was? The first night I slept so well, however about the 3rd night I woke up with severe pain in my upper thigh. Pain is increasing I need help getting out of bed and in and out of my car. Pain doesn't decrease by evening. I feel like I am losing use of my leg. I'm scared.
