I have also noticed that the area around my mouth (“muzzle”)is cyanotic. I am not finding any information about it, except when it is associated with infant congenital heart disease, which, btw, my 3rd son has. I asked my pcp last time I saw her, but she didn’t have an answer. I think she is beginning to get overwhelmed with so many unusual symptoms. I am wondering if the cyanosis could possibly be ccsvi-related, and if I should be concerned. The livido reticularis has not subsided, both started at about the same time. I notice that with the motion of washing my hands or even putting on lotion or pumping my fist, the l.r. in my arms gets more pronounced. Maybe that’s normal, I don’t know. Thanks for any ideas.
