Classic migraines late in life

Hi, I'm new here and have been having classic migraines for 3 - 4 years. They started when I was 73! I just wanted to respond to Butterball 1950 to let you know that I was diagnosed with occipital neuralgia, too. I also had the nerve block (did nothing) and had the facet joints at C2,3, 3,4, 45 injected with lidocaine and steroids. I've been dealing with recovery of this, going to physical therapy to stretch and strengthen my neck muscles, and taking Topamax. I took Gabapentin as my first therapy, then Elevil, then Topamax, then Verapamil, then Inderal, now back to Topamax and Atenolol. Along the way I developed chronic steroid-responding glaucoma. So far, my best result has been from PT and the facet joint injections. My neurologist sent me to a neurosurgeon, I had MRIs of my neck and brain and then the neurosurgeon sent me to a Pain Management doctor for the cervical injections. I am now finished with Topamax since I developed a sensitivity to it which caused vasculitis. After 12 days of tapering, last night was my first Topamax-free night, and I immediately developed an aura + headache upon awakening this morning. My doctor has suggested Procardia as my last ditch migraine prophylactic. Has anyone else tried this drug? Sorry this is so long, but thanks for "listening."
