I am an avid hiker, biker kayaker etc. For four months I've been unable to lift my leg without pain. Example, getting into a car. I have to lift my right leg. To cross my legs when sitting I have to lift my leg. It is undiagnosed but my GP sent me to Physical Therapy. They have no idea, but have me doing pilates style exercises. Nothing is changing. I'm worried, frustrated and miss my life the way it was. Any ideas what this might be, what type of Dr. I should see? Help
