Good point we should ask for non-medicated responses! Muscle pain is a big part of my post exercise symptoms....except that its different from my pain from exercise prior to CFS - its a burning pain...not an aching pain...
If we consider the current poll to be symptoms that persist even with treatment, it looks like there's a pretty clear group of 3 that would not necessarily be expected from "typical" overexercising -- severe fatigue, flu-like symptoms, and cognitive problems. However, they sound like pretty common reactions to exercising when you have mono, for example.
My muscle pain happened in 2 types -- burning pain similar to the lactic acid burn of heavy exercise, and strange, dull joint aches that no OTC pain medication could touch. The first I don't have anymore since I don't push my body anywhere near that hard (as in walking for a whole block) anymore. The second wasn't usually part of the PEM, but more just part of a general flare or relapse. That one is usually handled with Cymbalta + OTC pain medication.
I wonder if we're all distinguishing an episode of PEM from general flares/relapses. I don't think the distinction was as clear to me when I when I was less ill than it is to me now....
