Something bit my leg and the bite mark keeps expanding

2 days ago, when I woke up, I felt as if an insect bit my leg. When I looked up to see what's happening, I noticed a small amount of blood that kept flowing. I went to the bathroom, I washed the area and I applied some medicinal alcohol. During that day...

I also took some Claritin (which is a drug that can be used in situations like these) and I applied some anti-histaminic cream. Since then, the bite mark keeps expanding, it's red, it's diameter has like 7cm, it makes me itch and right in the centre it has a white blain. I have no idea what bit me and what can I do. I can't go to the doctor until wednesday.

its probably a spider bite
but if it keeps expanding that cant be good
if its hurting or you notice a foul smell, open wound or different colour like purple or black starting to appear then it would be best to go to the hospital and let them take a look at it

spider bite most definitely
you need to go to the doctors immediately, or you could end up with heart failiure since the venom is still inside

first off, check under and around your bed, if you see a spider catch it in a plastic or glass container, you will need it so the doctors know what spider they are dealing with

DO NOT WAIT ANY LONGER ACT NOW

my friend had the same problem... she got bitten by a poisines spider!!! you probably got bitten by one!!! since the venom is still inseide of you it can attack the heart liver or other bodily organs!!!1 go to the doctor asap!!!

Sounds like a spider bit, try and find the spider and go to the doctor immediately to get one medication, because spider bites can expand and leave really bad marks in your body.
