Hi, I had Botox injections on October 15th. I'm a 2x brain cancer survivor and I've had bad headaches every single day since brain surgery. That was 11 years ago. So my neurologist finally suggested the Botox injections. Several people in brain cancer support groups have had great success. My problem is that I feel like I have a horrible whiplash. My head feels too heavy for my neck to hold up. I'm constantly looking down & when I try to lift my head and look up, it hurts like hell. If I have to turn my head sideways it hurts. Has this happened with anyone else & if so how long did it last? My headaches are gone, even the barometric pressure ones. I'm thinking I deal with this for a couple of weeks for no headaches but really not much longer. I'm going to call my neurologist tomorrow, I just wanted other people's opinions.
