I went to the gym this evening and when I got out of the shower afterwards I noticed my ring finger was purple from the knuckle to about the start of the nail. It's just across the top of the finger.
Doesn't hurt, isn't swollen, is normal temperature. Didn't notice any discomfort at the gym.
I've removed my rings just in case it swells.
It looks like I've stained my finger with blackberries!
Any ideas what has caused it? It's a bit freaky and isn't fading
