Patient discussion about bleb
Q. What's the best treatment for a blister?
A. use a clean needle and poke a small hole right at the base, between normal skin and the blister. Push the blister down, allow it to drain completely and put a bandaid over it; don't ever rip off blister skin allow it to fall off or reattach naturally.
Q. What are the causes of viral blisters on the skin? For a few months now I've been having these hard viral blisters on my fingers. The only way to get rid of them is with freezed carbon. It does go away with that treatment- after a few weeks but then a new one appears. How can I prevent it from "attacking" again??
A. These viral blisters you are describing are caused by HPV (papilloma virus), and are very hard to get rid of without treatment with freezed carbon. Many of us have the virus but not everyone gets the actual infection. There is not a proved way of preventing from it to happen again after treatment, unfortunately..More discussions about bleb
