Hello, I get botox injections q3 months for chronic migraine . However the past two weeks or so I have been waking up with a low grade headache and nausea almost everyday. My headaches in the past have been inconvenient, and easy to nip in the butt if I take my relpax at onset of symptoms, but I have never experienced as much nausea as I have the past couple of weeks. I ve taken zofran and phenergan a few times for this nausea, but with very mild relief - the nausea starts up again approx. 2 hours after taking the med. Any ideas? I am a 30 yo F, never pregnant, using Implanon for contraception . Thank you.
