Hi, thanks for writing to HCM.
I personally think that no treating doctor can assure you a complete cure for tennis elbow
If conventional modes of treatment with medicines, physiotherapy
have failed to provide pain relief, then a local steroid
injection into the point of maximum tenderness will provide significant improvement.
It is very essential to avoid any form of movement or activity that causes pain.
Surgical release of the common extensor origin is the last option for treating tennis elbow.
Hope this information is helpful. Good day
