do Ты know how to get rid of blisters fast

Pop it.

Common sense bro.

Get a needle and poke it from the side.

Instead of popping it yourself with a needle Ты could try bathing your feet and ankles in warm water. Not boiling, but not tepid either.
It usually takes around 2 days constant bathing, drying, changing the water etc to pop them.

Or, like others have сказал(-а) - pop it with a needle. But make sure Ты sterelise the needle first by putting it into a cup of boiling water for a minute. If Ты don't and the needle has germs on it, it could do еще damage then good.

It depends how big it is, still pop it.
