blue fingernails with hypo?

[hcurrie]

hi today my hands are cold and my fingernails have just the slightest tint of blue to them i am also weak (my thyroid is getting pretty low t4 ) but i get this weakness a lot i checked my bp and it was fine 120/74 heart rate is steady no pain or anything, my lips are not blue - i called the endo and she said low thyroid would not do this so not to worry, i was wondering if anyone else had this? i know we have a lot of symptoms that the docs do not recognize so..... thanks in advance

Raynauds started for me about 1 year after removal of my thyroid.  i did recently have my synthroid increased and it does seem better.  ironically my dr. has it as well and we live up north - she said the best thing to do is to try to keep them from extreme changes.  i walk in the cold everyday for exercise and i bought great gloves with liners, and it is usually fine.  i actually have more trouble reaching into the cold case at the grocery store.  my dr. said it is nothing to worry about - just try to keep them warm and prevent those extreme changes.    by the way - my symptoms are they feel painfully cold, and turn white -- sometimes it is all fingers, sometimes partial -- then as the blood starts to recirculate, they turn blue before becoming normal.  wierd - huh?

Are you anemic?

Get a CBC as well as a Ferritin blood test. The ferritin will show how much iron you have in storage. It can be low even if the CBC is normal.

Or Raynaud's Disease ?
"Raynaud's disease is a condition that causes some areas of your body — such as your fingers, toes, tip of your nose and your ears — to feel numb and cool in response to cold temperatures or stress. In Raynaud's disease, arteries that supply blood to your skin narrow, limiting blood circulation to affected areas"
-Mayo Clinic

I get the blue tinge on the fingernails too, plus tingles & numbness occassionally if I raise my arm up. I'm hypoT also.

The past couple of years I've noticed that 1/2 of my hand/fingers turn blue, usually after I shower--even if it's a hot shower.  Weird....  My left foot has been turning blue, when I'm sitting or standing for 15 minutes or longer,  for a few years and I've been diagnosed with chronic venous insufficiency--varicose veins, worse on the left cuz of pregnancies, I was told.

Maybe it's Reynaud's syndrome?  Maybe due to hypo, maybe not, who knows?
