I got a cut on my finger might be infected... help =] ?

got a tiny cut on my little finger, went all white and pussy around it, i popped it and washed it and put lavender oil on it... helped a bit but didnt take down the swelling...

Every now and then i can feel a kind of pain jolt through my arm down through my body but is most painfull in my leg... it starts in my finger...

Any help would be apreciatted =]

Sounds pretty serious. Go and get it seen to by a doctor ASAP. Keep the wound clean and put some antiseptic cream on it. It might be wise to cover it with a plaster to prevent further exposure to infections
