So yesterday I was deadlifting and felt strong, so I decided to go for a new PR. I hit it, and it felt good. I did one more single, and it was a struggle, so I called it a day. I woke up with some pain in my left lat. It is sore to the touch, but not excrutiating, and massaging it helps temporarily.
If I lift my arms above my head, there is a serious bulge on the left side of my ribcage coming off the bottom of my lat. I would think it would hurt more, though. I can also do pullups without much pain. What gives??
