Anyone had thermo shock before?

yesterday night I was in bed and wake up shaked and it went on for a good 45 mins chills stuck in my back and wavering movments of the body, the temp in the house was at 75 and my bodys temp was not frezen but my brain thought so. is this a side a fact of my meds or so other illness?

My brother went through this when his meds were changed by too large of an amount too quickly, but it’s also a symptom of the flu.

I had this but it wasn’t because of a med change. I was in bed and fro some reason the 2 full sized blankets I had weren’t keeping me warm.
