Just to add, SGB are pretty routine at pain clinics and you should have no problem finding a doc in San Diego to perform the procedure, just verify if they do them blindly or via fluoroscopy. The results should last longer and there is less risk of spread if done via fluoroscopy. I've gone through both types... The first via a pain center doc, the second via an ex spine surgeon. Very different procedures and results.

Many docs treat these just as diagnostic blocks. NOT what you want.
