[QUOTE=chamade;458858]Pain can have a negative effect itself on the course of any illness, as it increases stress.
I am in the same boat, I went running around the GG Park 10 days ago and I am still paying for it. I was fine for the first few days after running but then all hell broke loose - burning, deep aches, stinging, twitching.[/QUOTE

Very true about the stress chamade. Yep, it seems like I am also having a delayed effect after the activity...
