Lately (past few months maybe) I've occasionally looked down at my fingertips and noticed that they are blue/purplish. This is especially visible under my nails, which turn a lavender bluish color. It's not related to temperature, as my hands can be very warm when this happens. I think it might be blood sugar related...when my BS is dropping quickly or is low I often notice it happening more.
I am T1 and also hypothyroid, but am up to date on medication. I've just changed endos and I'm not too keen on my new one...she skipped out on a whole bunch of tests when I saw her a month ago, so I have no idea if there's anything else going on! My last A1c was 11.
Could this be diabetes related or something else? It's not painful, but it does really creep me out to have to do a finger prick on a blue finger!
