Thanks again, to all of you. You're really helping me keep this in perspective. I guess the thing that really set my anxiety off tonight is that I saw that horrible disease which shall not be named could start in your hips. Both of the quads/thigh have seemed weak to me lately after excessive walking or running or squatting and that's what set me off. However, I should keep in mind that the disease only strikes one limb at a time and that if I can still run, stand on my toes, heels, balance on one leg, and the fact that Im 21, then I guess I should be okay.
None of these problems started until I began working as a cashier and standing long hours of the days in bad shoes. I wonder if the strain of standing all day could have started causing me these problems.
