Just wondering if anyone’s had anything like this

Got bitten on my foot. I did scratch it a bit. It swelled to golf ball size, red and hot to touch. Foot hurt to walk on / felt like someone trod on it. Swelling was pressing on the nerves I think. Lump swelling went down - but left a red patch, that spread to most of my foot. And I now have a fever of 38.3 and resting heart rate of 71 (normally 60ish)

That foot feels cold to touch, also, and the leg. Other one is fine.

Just thought if anyone has had a similar experience and didn’t end up in hospital, I’d calm down. 🥺
