Stop in for a cup of coffee

Leg swelled and got sore. Both thighs felt like I ran a few miles. Got very tired and worn out.
That does not sound good at all guy, symptoms staying in line with prognosis? That would be freaking me out. Your base line for health is way beyond average due to all the physical training you do. Something sounds amiss?
