I had Botox injections 3 times in my life. After each time I get terrible headache(cluster headache ) that awaken me from sleep. It lasts usually 10 days after injection and gradually lose its intensity. I think it is not coincidence to have headache after each Botox injection. Do you think Botox affects trigeminal neuralgia? My doctor who injected me has no interpretation on what is going on. I really regret injecting Botox. My life has became terrible due to the cluster headache
