@orienteer I am so sorry to hear this. I passed 3 years in February and am still dealing with a constant headache. I still have really bad days and some not so bad days where I can function relatively normally. I have tried 30+ migraine medicines and am getting some relief when using my emergency meds Ubrelvy or Fiorect immediately when I feel the onset of a bad headache starting. My neurologist I’d treating me as a migraine patient and the drugs I am on now include the 2 above, plus Ajovy once a month, Botox every 12 weeks, and Symbravo and Acetazolamide which I take either or both with Ubrelvy or Fioricet, if the pain does not improve. They all can make me drowsy or sometimes dizzy, but better to feel that way then a debilitating headache. The limited 8 pills of Ubrevly a month make it difficult to decide if the headache will get bad enough to justify it, but if I take them at onset, they really are helping me recently. The amount of drugs you need to trial before you can get any of the above drugs is maddening, but once you can get these prescriptions, I feel they are helping. I have also noticed air pressure changes can trigger headaches as well. My biggest culprit is stress. I also occasionally take Clonazepam or a muscle relaxant like Cyclobenzeprine (but not together!) if the headache just gets moderately worse. Hang in there! I typically check this website several times a week. I am happy to help with any advice or questions you may have. I hope you find good doctors to help you manage this. Please share anything that you find helps you. My best guess is that we both had nerve damage during the balloon sinuplasty.
