My toes have recently started changing color, certain times one or more of them will look blue. That is a new symptom for me and scary.

Is this normal?

Stacy, some of mine are often blue--fingers also. Others will be bright red. The rheumatologist and PCP both suspect Raynaud's (though I have trouble with heat more often than cold). I think there's been some discussion of Raynaud's here; have you checked for that? If it's the primary symptom, it's evidently not dangerous. But I think it can be secondary to some other things.

Color changes occur with circulation issues as ChaucerFan explains.
There are so many causes for Raynaud's...I've seen lists pages long!

But color changes also come from RSD... now called CRPS..
We have an RSD forum here.

The most common cause of Raynaud's in women is autoimmune disease. Lupus in particular. But the other types of autoimmune diseases often affect the circulation.

I'd see what your doctor thinks.

So my Hashi's is auto immune, could this be a cause?? I plan to but I dont go to my dr for another month.

The autoimmune diseases tend to cluster. So if you have Hash.. you might have another.

Until your appointment, just when you see the blue toes, gently put them in lukewarm water, and see if they resolve. Do some experiments within your comfort levels to see 1) how long they are blue..2) if warmth reverses the color blue, 3) if your toes go very white often, 4) does this happen when you are hungry, and may be low blood sugar related? ... or 5) is there no trigger obvious or rhyme or reason? Things like this...details before your next doctor visit.

There is a condition connected to overuse of Tylenol...it changes the hemoglobin in the blood and creates a blue tint. But it would be a general effect and not confined to the toes.

I did know a gal when I was in art school, and her lips would get blue alot.... and she took HCTZ daily too. I always wondered if that drug was causing, it, because she is in her late 70's now and still alive...so the blue lips were not an ominous sign of lung or heart disease (she was in her 50's then).

Make sure you drink enough water and your blood is not too thick due to dehydration.

There is a condition sometimes connected to thyroid disease (hypo forms) called mucinosis -- which is a deposition of mucin in the tissues.

Presentation of this varies from person to person.

Raynaud's can be a precursor to a lot of diseases.

Best to find out if you do indeed have it. If your fingertips start peeling, cracking, open sores you do have a big problem.
