So the other day I decide why not hit my biceps (virgin muscle) instead of my quads just to get a little fascia stretching.
Couple of days later the primo pain is gone in my left arm but my right arm is even more painful then usual and quite red.
I wait 2 more days to see if its gonna go away by itself but I'm shit outta luck.
Go to the doctor and apparently its cellulitis and she put me on strong antibiotics right away.
