Hi, I had about eight spider bites, three around my neck and the rest on my stomach, the spider must have crawled into a jumper - I should have got some treatment as I really suffered,the bites were huge with enormous red saucer type marks around and they felt like they were burning - they still keep flaring up - GET SOME ADVICE - see the doctor or a pharmacist - you may need antihistamines or anti biotics if infection starts - but dont leave them/it like I did.
If your face is swelling I wouldn't mess around, you might be having some sort of systemic reaction to whatever venom from whatever bit you...you need to get that checked....that's too scary to just guess about
