I've been squatting for a couple months, and I've taken my back squat from pathetic to not-as-pathetic. The weights have started getting heavy for me (3x3@285), and I've noticed something strange. When I strain on the squat, I feel an intense burning soreness in my jaw and the front/sides of my neck (around my throat). It's really strange and uncomfortable. My legs and back feel pretty good, but my goddamn jaw and throat aches?!?
Anyone else have this? What does it mean? I guess I have weak jaw and throat muscle, unused to such strain? I assume it's nothing to worry about, but I wouldn't mind some reassurance.
