Is it just your arms that are blue? And the right started before the left?QYes, just my arms. The left one started turning blue before the right one, its the blood oddity that started in the right. My lips used to also occasionally turn blue months and months ago, but now its strictly my arms.Sorry it took so long to get back to you things have been crazy on my end with covid. Ive been thinking a lot about your case over the last few days. I think its really strange that its only your upper extremities that are changing color. Please keep an eye out for color changes on your legs or other body parts. Typically when there is some form of differential cyanosis (one part is blue and others arent) we think of cardiac defects and if its one specific limb poor perfusion. But given your age and normal echo a cardiac defect causing your symptoms is unlikely. My next best guess would be something like pernicious anemia/B12 deficiency. This could explain your developing anemia and some of your pain symptoms. The blue coloring could be due to easy bruising related to it. However given that you have microcytic anemia (small red blood cells) and we typically see a macrocytic anemia (big red blood cells) with pernicious anemia/B12 deficiency. But that doesnt necessarily rule out that as a cause for you symptoms. To evaluate this you would start by checking b12, folate levels. Like other have mentioned you could have a hemoglobinopathy causing the cyanosis and anemia which would be more consistent with your microcytosis. However I would have expected this to show up before now, have some known family history of anemia or bleeding disorders, and/or have cyanosis or bruising on more of your body than just your arms. My best guess would be some kind of vasculitis causing vasospasm in your arms giving them a cyanotic appearance. The vasculitis could also be causing the pain you experience in your legs. Your developing microcytic anemia could be early anemia of chronic disease with maybe a pinch of iron deficiency thrown in. Id recommend asking for a ferritin and iron level to evaluate the anemia more. In terms of vasculitis workup, its a bit out of my wheelhouse so Id recommend considering seeing a rheumatologist for further evaluation. Those docs typically (or at least the ones I have worked with) are more of the safari guides than other docs and specialize in zebras.Tl;dr: Possibly a vasculitis, consider rheumatology. Also could be B12 deficiency/pernicious anemia or hemoglobinopathy but less likely due to nerd stuff as above.*edit: Like to add that you should probably also consider seeing a hematologist as well if you havent.
I put it in my post! Theres a lot of screenshots lol, so beware, but its every test result Ive received most recently (September 11th).
