purpledaisy, my neuro prescribed lidocaine nasal spray for me several months ago. He said he wanted to try it to see if it could give me any relief. So far, it hasn't done much to help me but, my pain is always in the center of my head, behind one eye (usually my left eye). The lidocaine nasal spray works best for pain in the front part of your head (whether the pain is on one side or both sides). I really think that if your pain is in the front part of your head, this stuff would be great. Basically, what it does is numb the area that the spray can reach.
Hope this help. Please let us know how this is working for you.
