Hey guys.. i was just wondering if this has happened to anyone before.. I was doing back today, and did a lot of lat work(rows/pulls) got a crazy pump.. so i'm changing my shirt after the workout and on my lats, near the middle of each of them there's what looks like rugburn, lots and lots of tiny red dots.. They're like 2 square inches each, and i have no idea what they're from. Anyone shed any lights on this? i'll take a pic tomorrow.
