In the past couple of months I ve noticed my r. Leg/ foot colder than my left. I have arthritis in my hips, have developed a slight limp, and decreased ability to squat, sit sideways on legs or open my legs wide in a pulled up position, or pull legs into body ( as in putting on tights) due to pain. Trying to do stretches and exercises given me in rehab therapy, but rather slow going and never noticed the difference in temp between left/right leg. What s going on?
