On Thursday night I thought it was a good idea to use my hot glue gun and scrape a bit away forgetting it was 200C I now have a massive blister on my pointy finger. Allowing for the fact I’ve managed not to burst it yet - is that the best course of action or should I take a pin to it?
As tempting as it is to take a pin to it, try not to. Apply ice pack or packet of frozen veg wrapped in a tea towel every few hours, and let it recover naturally. Any puncture of the blister invites infection.
Cover with a light dressing if its vulnerable to damage.
