Any ideas what this might be?
I probably would have written this off as some sort of insect bite except this happened on the same finger joint about a month ago.
First time round my hands were a bit cracked and sore and I noticed that round the side of that finger joint was worse than the others (so I could feel it when I bent it). I noticed the skin was red sore and puffy (about a centimetre in diameter) and then little raised white lumps like insect bites showed. It was like that for a day or two, then gradually subsided away. So I forgot all about it.
Today I noticed that the same finger joint is sore again (skin not cracked this time though) with the red and puffy area. If I can look carefully I can sort of see a few lumps that look as if they're going to turn into those "bite" marks again.
It's really weird - any guesses what it could be?
