Pins and needles in left leg and foot?

[dangle90]

Wondering if anyone knows what this could be, for the past 4 days I've had pins and needles in my left leg and foot, constantly feels like when you try stand up after been sat on your legs for a while. Tried to get in at the Drs but there's no appointments until after Xmas.
Thanks

Back problems can cause this if you have a disc problem. Get it checked out and hope you feel better soon

It could also be a circulatory or nervous issue. GP!

Thanks guys I'm going to try get in the Drs tomorrow on triage. I thought back problems but I'm not having any pain in my back really :/

B12 deficiency
Google Pernicious Anaemia

Forgot to mention folate deficiency (& possible Vit D issues?)
