I am having intense pain in my legs, in particular, my right leg more than my left. After I have sat for an hour or more, I have a really hard time standing. I have to hold on to something and stand for a minute or so, before I am able to walk. It hurts to walk, but after I am able to move around a bit, it becomes much more tolerable. This pain feels like it is emanating from my bones, I have a really hard time climbing steps and lowering my body to sit down. I take one Tylenol to sleep, but after a few hrs of sleep, I still feel the throbbing pain. What kind of doctor do I see about this?
