Wrist spasms after wearing the Apple Watch

Why has my wrist started to spasm after wearing my Apple Watch series 7? I have been wearing my watch for about 3 weeks. Today I kept feeling very slight shocks it felt like alerts or notifications coming from the watch, but no such thing. After removing my watch I realized that I was experiencing wrist spams. This is not irritation, an allergic reaction, or the band being too tight. It is simply spasms which you can feel and even see after removing the watch. I’ve been reading other similar comments from Apple Watch users. This is disappointing as no actual answer or solution was offered. My wrist continues to spasm 🥴, why? I spent a good chunk of money on this gadget, the courtesy of a direct honest response would be appreciated, and please no references to the user manual.
