My pain is in my sacrum, left glute, thigh, and calf muscle primarily. It is rarely in all of these places at once. Sometimes at night, it feels like both legs are sore - the right only slightly - and sometimes I wake up with pain around both hips. My pain had always been limited to the left side prior. I'm hoping this means I've got my pain "on the run," but it's a bit too soon to tell yet.
