Robyn, if this is all within a few days, there's a chance these aren't as sports related as you think, but a virus. I've had that where I've had intense pain in one area, like a stiff neck, but that moved after a few days to, say, my knee. It started in areas that often hurt, then moved to areas that usually don't hurt. And I did not feel sick in any other way. It passed after a week, if I remember correctly.

Listen and be gentle with your body. You'll make it through this patch, too!

(and I won't bother with the list of things that are hurting on me this morning, and I didn't even try any new sport!!)

Hugs and butterflies,
