I had botox injections 5 weeks ago for chronic migraine. The neck spasms started ~5 days after and were pretty awful for about 2 weeks. Much better over the past week. The muscle relaxers prescribed by my dr caused hallucinations and sleeplessness. Ice on my neck helped. The spasms triggered more migraines. Right now, I wouldn't do this again but, if the migraines get much better now that the spasms have relented--I don't know. I'm curious to see if anyone tried a second time. Same outcome or different?
