Running after tommy john surgery?

I currently in my 8th week of rehabbing after Tommy John surgey and my doctor has cleared me for “Cardio.” Does this mean I can do running or is that too high impact? also, are high impact activities bad for my arm at this stage?

IF I recall correctly, I do think running is too high impact. All the guys in Cubs camp who had TJ spent many weeks on the exercise bike. I did the same following shoulder surgery. Keep your head up and keep working hard! We’re rooting for you!

Does Tommy john hurt?
