What's the fluid under a blister? What happens if I pop it? What happens if I were to leave it as a bubble?

I have a blister on the left side of my right forefinger from playing the drums...I know it's a friction thing because i've had them before but i've never really wondered whats beneath them.What's the fluid under a blister? What happens if I pop it? What happens if I were to leave it as a bubble?
Whenever you have a blister, you should leave the bubble over it. This protects the skin underneath from getting infected.
a: Puss

b: the puss leaks out and you feel better.

c: it'd hurt..it'd eventually go away..What's the fluid under a blister? What happens if I pop it? What happens if I were to leave it as a bubble?
thanks for giving me my first nausea of the day!
i am not sure what the fluid is but if you pop it the fluid will leak out and you will be left with an open sore and it will be easier for it to get infected. if you leave it alone it will eventually just go away,What's the fluid under a blister?

It's filled with pus. Don't pop it cause it could get infected. Let it go.
good question...i cant remember what the actual fluid is, but i do know that you should not pop them bc of risk of infection. the best thing to do is just put a bandaid over it until the fluid is reabsorbed back into your body. it should only take a day or two. i'll get back to you when i find out what the actual fluid is.



edit:

i posted a link on the treatment of blisters
The best thing to do with a blister is to let it be.



A blister is caused by excess friction. (Like you stated) and like most things on your body, it will only heal over time. If you pop it, it will hurt because you're exposing new skin. This might also lead to infection if it is deep enough
It's water. If it were puss, it would be a pimple. Take a thin pin and pop it, it will relieve the pressure. The prick will hurt, but the pain will stop. Wash it thoroughly, and put some antibiotic cream on it, and leave it open! It will dry out in a couple days (keep your hands clean) and the top will fall off, but the skin under it will be a little tougher. You shouldn't get too many more blisters. This is the way the body creates a callouse (tough skin)
I dont know what it is, but I do know, from experience, dont pop it. If the skin comes off that friction "burn" it'll be sooooo sensitive. It will basicly be an open would, suscceptable to infection, scabbing, scarring...it could get ugly.



I think its your body building a 'band aid' of sorts, to protect that area from being rubbed on, the friction, the burn. It uses a layer of your skin to make a band aid, then puts liquid in there to keep it moist and clean.



Leave the blister alone, but if you can't resist, poke it with a sterile needle, push the fluid out-it will be a little flat, then put on a band aid. Dont pick at it-it may scab up anyway if you drain it.



If you want to drum, put on a band aid or a terry cloth wristband to protect and prevent them in the future.
All the fluid is is just a build up of sweat under the surface of the skin. If you pop it nothing bad will happen but it may sting for a few days. If you leave it alone one of two things will happen: either it will pop on its own or it the fluid will actually get reabsorbed into you tissue.
