I had a nice little cortisone shot to the proximal fib-tib joint yesterday afternoon. It wasn't as painful as rumored but the lidocaine burned a bit like a bee sting. Afterward I stood up and have to admit the knee felt quite a bit better immediately. Then, like 45 minutes later, the lidocaine had worn off and the knee felt mostly the same. I'm supposed to see the cortisone take effect over the next week to 10 days. We'll see what happens!
Cranked some core in the evening; 43 chin-ups, 9 minutes of planks, a bunch of ab variations, and 80 push-ups. I'll wait a couple days before I try running or biking to allow the cortisone to do its thing..
