Questions about blood blisters?

This site has step-by-step instructions.

I think Step 4 might be significant for you since you are likely to continue having pressure at that site.

Just let it be, and your body will take care of it eventually. But a good tip would be to invest in a good pair of drum-gloves, so it won’t happen again.
You can drum again now, if you want to, as long as the blister doesn’t rupture. If it does, put a band-aid on it and leave it ‘til it’s healed.

I previously had a normal blister when I got the blood blister for quite some time, when are my hands finally going to form calaces? (spelling?)

is that why some drummers tape their fingers?

Yes, for padding and grip.

When I was a kid we always stabbed them with hydrogen peroxide covered needles… probably not medically sound but… [begin redneck voice] I ain’t dead yet neither [/end]

The problem with popping blisters is that it causes an open sore, and that hurts and could get infected. Best not to, but it won’t kill you, as @NaturalMineralWater have already found out.

In this day and age, with MRSA floating around in the community, I would strongly recommend against creating any unnecessary open sores that could become infected. Normal, otherwise healthy people die from MRSA infections. Don’t mess around with it.

I love dermatology. :)
Sterilize a needle and poke it out before it pops.
But maybe not blood blisters, though :S.
