I sometimes have trouble differentiating between normal muscle soreness and pain that has been triggered but I believe I have some similar symptoms after harder workouts...After longer runs sometimes my whole body is sore - example - yesterday I ran 8 miles and today my knees are sore which would be expected but also my wrists and knuckles are sore ... The pain is almost like growing pain they feel bone deep and a very hollow ache deep in the bone. I have had these body wide before. I assume this type of pain would not be expected without PN after a workout?
