i dont know if i pulled a muscle or if im just sore from working out, i did squats yesterday and today i flexed my back muscles and my bro said ther was a new muscle i could actually see and i looked in the mirror and i saw it. its a bump rite next to the center of my back, but it aint symetrical, did i pull a muscle on my back or just over worked my right side of my back somehow?
would it help if i get a pic on here?
