Thank you, tachead. I know what you are trying to say about throwing too many things at this at once, but really, I gave the verapamil a good 2 months, at least, to work & it didn't. Then we added depakote & prednisone. Nothing worked. I have since come off the verapamil & depakote & am only taking prednisone now. I just didn't want to continue with meds that weren't working. Also, I did stop the zyrtec 2 days ago. It was still the same. I know how important it is to give each medicine a chance, especially as it could end up being something that works & if I was adding everything at once I wouldn't know which one was the effective one. This spg block isn't a major surgery & it isn't permanent so I will give it a try. My neuro has said that the spg can be a pathway to all the pain, and the block can interrupt the pain signals to other areas. I've been dealing with these headaches for almost 20 years, and I am ready to get more aggressive, though. Especially since the prednisone isn't as helpful as it used to be.   

Thankyou Brew for your well wishes.

I will come back & make a post about it after it is done & tell everyone exactly how it was done & how I feel afterwards just in case anyone is interested in looking into it for themselves.

Thank you Joe. Pf days to you too
