Last week and again today I appear to have burst a blood vessel in my thumb.
I wasn't doing anything in particular (but was using my hands) and it just felt strange (bit tingly/numb/throbbing) and then bruising appeared very suddenly and it swelled up slightly.
It is now a lovely shade of purple/blue/dark grey around the inner joint halfway up the thumb and feels a bit sore/bruised.
It happened to me years ago and I vaguely remember the doctor saying it was a burst blood vessel but don't remember anything else.
Anyone know what causes it to happen? How it can be avoided? Should I be worried? Is it connected to anything else (eg Reynaulds?)?
Thanks
