Elbow discomfort after rehab

Hi i had Tommy John surgery 7 months ago and i got on the mound this past weekend for the first time. My arm felt good while throwing, and i tried to throw a couple of breaking pitches. Throwing a curveball felt fine but after i iced down and ran my arm really stiffened up. It is swollen and it has been for a few days now. Any comments? you think i might have just went in to fast with the off speed stuff? Or do you think it might be something more serious? let me know what you think. Thanks guys.

We realy can’t say much without knowing anything about your rehab and where you are with respect to that. What you wrote kind of makes it sound like you didn’t really ease yourself back into things.
