I usually do the heat therapy patches but the pain in my back is diffuse. I set a new PR yesterday with my deadlift (155lbs) and my last one I used all of my back and shoulder muscles instead of my legs, by accident (last rep, my hand was slipping and was about to drop it coming up and to keep it from dropping, I went poor form).
My back kills today, worse than my legs. The shitty part? Today is triceps and back. Lol
