Angi, I haven't experienced anything to that degree but we recently did a WOD that was 150 pullups for time with 3 burpees every 30 seconds and two of the women at my box experienced exactly what you're describing as far as the pain, soreness and the swelling. If you dont use it already I highly reccomend using voodoo floss bands (AKA mobility recovery bands). My coach wrapped the women and had them go through a bit of mobility on the third day (when it was the worst) and they were both amazed at the almost instant improvement and quicker recovery. I was skeptical but they're cheap (about $15 each) and they work. Some links on them below.

Thanks everyone! It really helps knowing I am not the only one who suffered from this. I might order the band, just to have them on hand for the next time! LOL, really I hope that it never happens again. I did ring rows yesterday morning in our wod. I did a scaled version.

I had some elbow tendonitis when I started CF. Once I warmed up it was pain free, just a bit stiff afterwards. Last year some time it just went away, haven't had that problem since.
