What kind of spider?
They said common household. I live in black widow/ hobo area. A little south of here it’s brown recluse. Allergies and infections can probably raise an ordinary spider to a new threat level. The infection is more likely the terminal threat. No treatment is pretty serious. I’ve been getting tetanus shots since I was a kid. Never let a scratch go untreated or ignored is my moto. I wish I could still get methylate. JMO
“It was found to be a common house spider...”
Based on the description of the bite site after a day or three, it was probably a brown recluse spider. They are about the size of a US dime, but pack a mean venom that will eat at the flesh. ...One of my employees was bitten on her belly while sleeping. She was in hospital for three days and was given lots of antibiotics to get rid of the infection.
The "brown recluse" in the United States would cause that sort of wound.
