So yesterday i woke up and my right pec is a little bigger than my right and I can't seem to figure out why. It IS sorer than my left so Idk. This happened when I first started working out back in May and I started taking crappy creatine. This time is different. The first time it felt like I was flexing it for about 3-4 days straight.......then it stopped and I had bad water retention underneath/below my right pec. This time it doesn't feel like its flexed...but just really sore and I'm not on creatine. any ideas?
