I wouldn’t sweat it too much. Let the doctor come back with his results in a couple of days. Stop playing Dr. Google because your only going to stress yourself out more. More then likely you were bit by a tick or maybe even a spider if you said you were venturing through the woods. You don’t get MRSA skipping through the woods. If you remembered pulling something out of your leg and it looked like a tick, more then likely it was.
I had a bacteria infection not long ago and thought it could have been MRSA too. It turned out to be Impetigo. It carries all the same physical symptoms to MRSA minus the EXTREME pain. They prescribed me some anti-biotics and in a about week and a half it was cleared up.
worse then google would be WebMD dont ever use the symptom checker, holy christ that thing will tell you either have a common cold or cancer…its ridiculous!
