Hello, I posted this symptom quite randomly in the questionnaire thread as I wanted to know if this problem had a particular name. However, a few suggestions came up as to what it could be so I thought I would describe my blueness and see where it led. I get occasional bouts of my fingers and feet turning a dusky blue. It has been as bad as the blue reaching half way up my calves. It's not painful and sometimes I only notice because I happen to have taken my socks off for a shower or something. I also suffer with my little finger going white and cold which is another circulation issue. I have seen a nurse practitioner after getting an emergency appointment and he told me it was because my body thought something bad was happening (fainting for example) so my blood was sent to my vital organs. He said it could have happened due to the temperature change of getting out of the shower (it was after getting out of the shower that I noticed the blue reaching up my legs). It was put down as an ME symptom. I don't know if this is related either but sometimes when I'm in the shower my palms go blue and I can see all the veins really clearly. Bit odd but it's another weird thing I've had for years. So far raynauds phenomenon has been suggested but I would have thought the nurse practitioner would have mentioned that. It looks to be the most likely if it's not just a nameless ME symptom. Ehlers-Danlos has also been mentioned but I don't fit the criteria for that being short and inflexible Blood pooling is another theory but I don't know much about that or whether it could be rectified. Any ideas? I'm not unduly worried but after all these years I feel I should know a little more about things that happen to me rather than just saying it's ME all the time.
