Is there such a thing as a non-headache migraine? My daughter was told that she has that. Her husband took her to the ER for difficulty in speaking, numbness in her extremities. She was told she had a non-headache migraine. I ve never heard of it before. She is prone to migraines, however, it always includes a headache. Also, what is a nerve ablation on the back for pain? Is it safe? Hows does one tell if they are hurting or injured in that area if the nerve is basically cut , as the word ablation means to me. Thank you for your help. YYYY@YYYY
