I've had a couple of times where a blood vessel, usually in my fingers, has just suddenly burst under the skin. It's very painful at the time but nothing much happens apart from developing a bruise. I haven't mentioned it to a doctor but having recently learnt my lesson about that (ignored symptoms for a couple of years, then found there was actually something properly wrong with me!) I think I should probably mention it next time I'm there? Does anyone have this and have found a reason behind it? I have been diagnosed with a couple of autoimmune conditions so am wondering if it may be linked to that somehow
