@teetee7 So the toradol shot worked just for that night? I'm going to make a claim without being able to back it up yet, and you and I might have just found a successful treatment for our sweats/chills completely randomly. So Toradol is the brand name for ketorolac tromethamine, an NSAID like Ibuprofen. Of all people, my gastroenterologist wrote me a prescription for 600mg ibuprofen when she asked about chest pain and I told her about how my ribs hurt... she thought it could be costochondritis and there was no harm in trying it out. I used to take 800mgs 4 times a day, nearly every day for pain since I was in high school. I finally stopped; figured I had put enough stress on my liver, kidneys, and was due for an ulcer. Anyway, after picking up the prescription, I didn't take it for a while because I wasn't eating, and I didn't want to take it on an empty stomach and get nauseous or an ulcer. I started taking it this past week, and now that I think of it, I either haven't had the fever-chills this week, or it hasn't been anywhere near as frustratingly bad as usual. Both toradol and ibuprofen are NSAIDs that inhibit prostaglandin synthesis. Prostaglandins are hormones that regulate homeostasis, inflammation, and act on the thermoregulatory center of the hypothalamus causing fever. Maybe we just figured out by accident that prostaglandins are the cause of this symptom of SFN, and NSAIDs can treat it!!!!!! If I'm right, I'll give you credit when I write the research paper on it, but I'm putting my name first, HAHAHAHA!
