Cortisone Shot or Tommy John Surgery?

Where to even begin... I would have considered myself a very lucky/healthy person when it came to sports related injuries (minus a shoulder setback and a broken arm) but nothing I couldn't play through until a little over 9 months ago in a game against Clemson. We were up by 3 runs heading into the top of the 6th and our starter was beginning to show signs of fatigue. I started to get loose in the bullpen but it was taking a while longer than usual (my thinking--> it was just one of those days) and I figured I would be ready by the time I got in the game. Coach gave me the nod for the 7th and although a little wild at the beginning I finally settled in after surrendering a run. I went back out for the 8th and right before I released my first warmup pitch I felt a sharp pain almost as though someone jabbed a knife into my elbow and twisted it.
