Hello Sharon,
I've had them, didn't do a lick of good. Just took me two to three days to get over the "procedure". The injection sites where PAINful. Frustrating I know! When I had them done over a years time (3 of them) I hadn't been diagnosed with Fibro yet. They were all done by the pain clinic. I personally had bad experiences with my pain clinics I went to.
Btw, welcome to the forum. Its the best place I've found myself for good info and a great place to get needed support.
Sending you a big soft hug your way.....
