See a doctor, physical therapist, physician's assistant or kettlebell instructor. (Or all of the above, preferably.) Get your specific medical issue addressed. Fix whatever form issues you have, whether related to the pain or not.
Without attempting to diagnose you over the internet via a one-sentence description of your problem, I'd bet that you have some form of overuse injury or tendon inflammation. It's also possible that you have gangrene or elbow gnomes. I'm not a doctor and diagnosis over the internet is inexact.
See a medical professional, see a fitness professional, get better, fix your form, get back into the workouts slowly.
