Hi. For nearly 2 months now I've been getting tingling and burning sensations in my face. Comes and goes, but I get it every day. Sometimes mild, and sometimes quite a lot of discomfort. Saw the GP last week and had a blood test. I've now received a text saying my Vitamin D level is slightly low and I should start taking a supplement, at 1000IU. Fine, but I've taken Vit D supplements of this type for years! I did swap to a lower dose 2 weeks ago as I started using a different supplement to help with arthritis and, as it has some Vit D in it,I stopped the separate higher dose tablet because I've heard too much But D is bad for you. I will now obviously swap back! But the thing that is troubling me is that I had these symptoms when I was taking the higher dose anyway. How likely is it that something has been missed?
