I had botox for migraines 6 days ago to be precise. About 2 days later to currently I've had a permanent terrible headache main I the bridge of nose region and my forehead which feels extremely pressurised and tight which is causing a horrible headache :( This was my first lot. I asked him to Inject less than he normally would as I'm sensitive to medications so he did about 3/4 My headaches are always at the back and I don't suffer with them at the front as I am since botox :(
