Skin, Hair and Nail Problems

I've had some itchy rashes on neck and chest area one day when I woke up. I took lots of water and had curd-water, rashes stopped itching by next day and started to dry. We're completely gone away in 5-6 days. This has happened after 10 days of going through deep dental clean up. The dentist assured that scaler and cleaning equipment were all sterilised and cleaned. Also, after a week from when rashes gone away, I was infected with Covid. What could have caused the itch rashes ? Note that pre rash days, I had little water and had lots of dry dates and eggs almost daily. Thanks.
