I am experiencing pain on the left side around my lower back area. A few days ago I noticed it and it was no big deal, but yesterday after I was done with my front and back squats, it started to hurt, and it ended up being hard for me to walk without feeling it. I remember this from a few months ago, that it happened after squats. It would hurt a little bit and then not as much on and off, but about a month and a half ago it stopped hurting completely. But now the pain came back. So does anyone have any suggestions for me or know what might be going on? It is strange because I can do all things like deadlift variants and heavy rows but once I started did squats the other day it came back and hurt quite a bit and it felt very uncomfortable to move around in bed or a chair, etc.
