So im 21w and the past few weeks (about 2 or so) i randomly get this horrid pain in my left thigh. Its on the outer thigh but kinda at the back..? Its a stabbing pain that bring me to my knees instantly. I cant deal with it.. I havent found that anything brings it on, it happens randomly for about 10-15 minutes. Any time i move my leg or put pressure on it during that 15 min, it just kinda crumples and i almost fall.. I try to stretch but i cant with my leg like this.
