In reply to shaymarriott:
I've got similar problems. I had it on the Right for about 18 months a couple of years ago which was a nightmare due to poor advice, info, research etc etc. I've now got it on the Left and managing it better.
I think it's important to be sure of the diagnosis. If it is golfers elbow or medial epicondylosis then find out as much about your own upper body as possible - physio etc, this will help you tailor your rehab.
The things I think are important:
Don't get an injection - there's evidence to suggest it will make it worse.
Start with low weight and build up - I was using only 1 kg for eccentric wrist extensions at the beginning.
Only exercise as pain allows, if you feel pain it is likely making it worse.
I do regular stretches, push ups, eccentric wrist extension and supination. I have stopped bouldering and using the finger board. I'm only climbing routes - as pain allows.
Good luck.
