REST THAT ELBOW - AND KEEP IT RESTED!
Is it in a cast?
I'm saying this through a TON of experiance, i've broken my elbow several times, and because of overworking it, I have damaged the bone and ligament, had to have an op a few weeks ago to remove the radial head because it was irregular shaped! I'm not even allowed to swim until I go back to the hospital. thats 3 weeks away and my op was 3 weeks ago!
Try some nice steady paced walked, I am VERY aware that walking can jar and jolt it, but walking would be nice excercise.
If it is in a cast, then just try and move your fingers, it will help you in the long run, and help reduce swelling - after a few weeks the cast might start to itch - after all the casts I've been in thats usually a good sign.
I'm not in a cast at the moment - I'm not worrying too much with weights, at least with upper body because it hurts. don't do anmything that hurts, that is not very wise, because you'll linger/damage yourself.
you need to give your elbow time to re-heal. I'm not allowed todo anything that in involves my elbow for 6 weeks. it needs to heal, and I do not want to go back into that op theatre again!!!
You broke it yesterday? I wouldn't think about excercise just yet, I can't walk for longer than 5 mins after any op/ break on my elbow for the first week.
Sorry if this is kinda long, I broke my elbow 3 times and have had 2 ops on it - so yeah, just horrible experiance.
I'd just watch what you eat for now!
Hope you recover speedily!
