After spending the whole afternoon stripping a door, I've ended up with a blister on my finger that feels like a burn. I'm uncertain whether it resulted from the chemicals or the heat gun. My mind is getting paranoid, fearing it might dissolve my finger bone. Additionally, my knuckle feels tight and swollen, likely from overdoing the scraping. The stinging sensation is intense. Unsure of what I need exactly, perhaps just some reassurance. Can someone give me a shake, I suspect the chemicals might have left me feeling a bit off.
