Delayed Onset Muslce Soreness if anyone doesn't know what they are. I'm very familiar with DOMS form lifting but they were alway localized to the muscle groups worked. Lately I've been working a lot harded in the pool and about 30 hours later I'm in systemic pain. It starts at the top of my glutes and goes all the way to the base of my skull and its I deep down sorenes unlike anything I've ever felt before. It lasts over night and the next moring I'm fine. Is this normal?
