Tennis Elbow

hi, ive just been to my gp and told i have tennis elbow my doctor gave me a prescription for depo medrone injection to relieve the pain has anyone had this-did it work?

If it is like Depo Medrol, I had injections in thumbs for OA. Injected at pain point and was pain free for about 5 months.
Hope this helps.
