Hey all. Two days ago my fingertips turned blue . went to the hospital to check it out, they said it was Raynaud's and it was perfectly normal. I don't know if I should believe them because there are also blue dots on my wrists that go away. Also there are blue veins that are visjble on the right sids of my left knee, I'm scared its a blood clot or a broken vein? I need some reassurance asap I am terrified.
