I have had daily headaches since December 26th 2005, no reason for it. After several months of CTs, MRIs - and lots of medicines.... no relief!!! Recently I have had several C3 injections, with a right C2 injection this past Thursday. I have another scheduled for this coming Thursday. Dr. Hamza is talking about doing a Cervical Spine Stimulator..... can anyone give me more information on this?? Any help is appreicated
