I've had elbow pain as well after doing pullups. For me it hurts on the inside part of the elbow (if you hold your arm palm up, the side of the elbow that's closest to your body). I should probably get it looked at by a physiotherapist or some such expert but being stubborn, I thought I'd try and fix it on my own first.
I think I've finally concluded that in my case the big contributing factor to my pain was bad form during pullups. I think that the way I twist my arms when taking a wider than shoulder width grip was putting a lot of stress on that part of the elbow. That and bad kipping on later sets (have to work on that kipping), combined with being a 220+ lb. guy all finally ganged up on my elbows.
So I've started to do the following:
- I'm using different hand spacings for pullups
- I'm not arcing my back so much, instead I'm trying to keep my body more straight, this seems to put less stress on my elbows
- I've been doing some light curls after my workout (I think my triceps are a lot stronger than my biceps, partly due to previous training, and this was contributing).
- I've been cutting back on the pullups a bit to give my elbows time to recuperate (I do some type of row instead those days because they don't seem to hurt)
- I apply ice afterwards
I'm still feeling a twinge now and then but no where near as bad as it used to be.
