So I began lifting ~2 months ago and everything was going fine until last week. For reference I add 10 pounds to my squat every week since I started out super week. A few days ago I finished a set of squats and felt an awfully intense throb on the left side of my head, then tingles, then numbness. It went away for a few minutes but I’m very reluctant to do squats again. Has anybody else felt this before?
