OK, I've just about had it with this ache! I've been dealing with this now for about 4 yrs...it can be one buttock OR the other, or BOTH...at the same time, my thigh muscles ACHE SO BADLY I have to take Advil. Latley, the muscle on the left side of the shin bone (on my LEFT calf) is hurting too! The ache next to the shin bone comes and goes, but the ache in the thigh is almost always there, the worst leg is the left. (same for the butt, it's mainly on the left). It hurts to walk up my front stairs, I've dealt with that now for a few years, it has it's GOOD days, and it's BAD days, some days worse, some days better. WHAT THE HECK IS THIS? WHAT DO I DO? I can't even work because of this. Oh, and then, my right HEEL is hurting now. Just to fill you in..yes, I'm about 40 lbs. overweight, but like wow, that's not the end of the world here. Plus, I had this leg ache for a few yrs BEFORE it was a whole 40 lbs. overweight. So, WHAT THE HECK? If anyone has any info on this, I really need it.
