Emergency help!

So I’m a little worried but I don’t want to go to the doctor if it’s nothing serious. So some may have seen my post about how I got burnt. Well I woke up this morning and I felt a lot of pressure on my ankle but I didn’t think much of it. Well then I look down and my ankle and calf is really swollen. You can see the burn and the comparison between my other ankle. I’ve been drinking a ton of water and I’ve been peeing fine as well so I don’t think it’s retaining water what do you think? It also feels tingly everywhere when I’m walking and when I’m sitting it’s tingly on my toes.
