Last night I went to the emergency room after experiencing a horrible headache. I've been dealing with headaches that occur daily at the same time multiple times a day for the past couple of months. My neurologist cannot give me a diagnosis because it is not 100% consistent with cluster headaches or migraines. At the ER, I received an IV cocktail of dexamethasone, ketorolac, sodium chloride, diphenhydramine, and metoclopramide. Within 60 seconds of the dexa, I had the worst crotch burning of my life but stayed composed and said everything was okay. The dude pushed the medication in so fast I could physically feel it rush in and it felt so awful. I do not remember the order of the other medications, but I remember feeling like I was going to faint, fading in and out of consciousness, I felt so anxious and frustrated I wanted to rip out the IV and escape, I felt like I was going to die. My anxiety shot through the roof and I desperately looked around. I felt like I couldn't breathe and like my heart was going to exert itself at any minute. I had horrible tremors and my teeth chattered, so I was given blankets. Shortly after the benadryl I think, I felt the weirdest sensation throughout my body and wanted to cry so bad, but then I had to suppress fits of laughter because I wanted to just burst into laughs. I kept composed and told them everything was okay and only let them now about the burning and the tremors. Should I have said something about the psychological effects I was feeling? I have a habit of downplaying things. This was the worst l've ever felt. It felt like a bad shroom trip, or when I OD'd on benadryl once. Pure anxiety, desperation, and just feeling out of touch with reality and myself. Maybe I'm downplaying it in this post, but just know it was the worst l've ever felt. I was like "why didn't I just stay home dude..." After my benadryl nap, I felt good though. Today, I still experience random burning down there and then it goes away and comes back minutes later Helppp!, I just want to know if I would've had valid rea to express these concerns.

Edit: all day I’ve been having troubles with temperature dysregulation, something I noticed happens sometimes after starting the antipsychotics. But today it’s been like constant back and forth of being hot and sweating but then I get cold at the same time
