I have to chime in on this one. My labs have been normal also and my top half (was mostly in my biceps) is normal but my legs are a mess. My thigh muscles hurt under load tremendously and are very stiff. They don't hurt at rest or if they are moving and not weight bearing. I bet dollars to donuts that my rheumy isn't going to buy PMR in only the lower half of my body. And I don't want any more pred anyway. I have glaucoma and my opthomalagist would freak. But what the heck is it? I too have to crawl up the stairs and I come down on my butt. Not too glamerous.
