I tried botox quite a few years ago the Drs have to be careful where they inject mine hit some nerve and it affected the whole back of my head and neck triggering tension headaches. I couldn’t believe it! Now I’m getting migraines again with visual disturbances. My headaches are / sinus/allergy/stress related. They’re aweful again. I had s cats scan last week of my sinuses. It showed inflammation. So now I’m just waiting to see what the doctor suggests. I also have a neurologist on the list too . So sick of drs!
