Thanks Spiny! I'm glad the procedure went well for you. I agree that a pre-op talk stressing the importance of the protocol you need can make all the difference in your experience. In terms of anesthesia, if you need it again Propanolol might be worth inquiring about. I have heard more than one buster claim that it had been helpful for them and the Chicago Headache Clinic considers it as "occasionally helpful for preventing Cluster Headache. (there have actually been reports of it preventing clusters since 1972 but for some reason it is never mentioned) If you need anesthesia again it might be a better option than some of the other anesthesia drugs.
In regard to nitrous oxide, Quite a while ago I got pretty sick of all my dental work. It is always complete torture. It doesn't matter if it is a cleaning, a cavity or a root canal--they all leave me in excruciating pain regardless of novicaine and then I always leave with either a cluster or a migraine. So I started looking into nitrous oxide and had the same thought that Jon had, that it would probably be a trigger. I was surprised to find that the only info I could find on nitrous and clusters was a report on Erowid by a high school kid that had clusters. Truthfully it gave me a lump in my throat, thinking about high schoolers having to deal with chronic clusters. That is just wrong and eggs me on, we need to change this situation. It is simply unacceptable.
So the report I found by this high schooler said that he had chronic clusters and managed them with nitrous oxide. (https://erowid.org/experiences/exp.php?ID=23397) He said that he would bringe a small nitrous "cracker" (device used to open a small nitrous cartridge) and any time he felt a hit coming on he went to the rest room and took some nitrous, claiming it worked every time. After looking into it I realized that his claim was not that weird. Nitrous is in the same class of drugs as another cluster drug, ketamine. Both drugs are NMDA receptor antagonists, both lower nitric oxide levels, both lower TNF levels and both are known to be very effective for pain. Hell, in some countries they give nitrous oxide to women for childbirth.
So I was at least convinced that it was not going to trigger an attack for me and I made the appointment with a new dentist. I had 2 or 3 times where I went in and everything worked great. Not long after the shot of novicaine they would put the nitrous mask on and I would experience very little pain and no cluster or migraine afterwords.
Then one day the hygenist goes to give me a shot of novicaine (before I get any nitrous) and puts the needle straight into a nerve, I'm guessing she hit my trigeminal. Holy shit instant kip 9 cluster! I pushed the lady off of me and jumped up looking for my bag that had my sumatriptan shots. I found it and was fumbling through it, blurring vision, eye tearing, red hot poker love smashing through my eyeball when the hygenist walked in with the nitrous. I gave up on the sumatriptan, and told them to put me on full blast. Luckily they complied. Truthfully they looked so damn scared and in shock of the situation I think that I think they would have done whatever I asked at that point.
Within seconds of the nitrous the pain ramped down. A full minute or two and the pain was 100% gone for the rest of the day. Since then I have made them put the mask on before they do anything to me. They always try to wait on it but I give them the look and state "NO ONE touches me until you put the mask on."
Thanks again for sharing Spiny
