Golfers elbow

I have suffered with accute pain on the inside of my elbow for more than two years.
I have had the following treatment.
Cortazone injection x 2 ,ultra sound. acupuncture,physio therapy,Voltarol diclafenic tablets for two years.The only thing that has helped is the Cortazone injection but only lasted for about 2 months. The Voltarol tablets also help but I cannot stay on these for ever.
