First I would think ice, rest and there is a lotion that kind of works like Advil.. sorry forgot the name.. if it comes to me I'll post it. It is a prescription lotion though.

this may come a bit late (4 years!), but I recently began prolotherapy treatments for my shoulder and have had major positive results beginning with the very first treatment. I have also had treatments with a chiropractor in the same office treating the injury. I understand that is the way to complete and successful victory over the injury. My biggest challenge in the past 6 weeks of healing has been to remember the injury and not to move in a way that may re-injure before the healing is complete.

Surgery has a low success rate because people return to normal activities too soon or go back to doing what caused their tennis elbow in the first place. PRP injections can be tricky because the Doctor has to hit the same spot on your elbow with each injection.

I would look into stem cell treatment. It has been showing good results with tennis elbow patients.

Good luck.

I found TENS treatment helpful....Walgreens has Icy Hot Mini Tens for $38.00
