The B-12 may help the tingling, as others have mentioned. However, there are several conditions which can cause tingling in the feet besides low vitamin B-12, including underlying health conditions or other deficiencies. For example, a magnesium deficiency can be a factor in peripheral neuropathy, include numbness and tingling or a pinched nerve.

So before starting any supplement it’s a good idea to check in with your doctor and maybe have some blood tests.

@preacherswife1977 I don’t feel tingling in my feet. My feet always feel like they’re numb. It’s a very strange feeling. It is always there. I notice it more at night when I’m laying down. Although, my hands and feet feel strange… It’s hard to describe.

I have neuropathy in my feet and hands, possibly due to being diabetic as well as having ET.
The past few nights I have been using my neuropathy relief socks. Bought them on ebay and find when I am having problems with my feet and not being able to sleep, I put the socks on and get a good nights sleep Don't seem to notice the tingling, numb feeling during the day, as when you have something else to occupy your mind, it goes into the back ground, doesn't disappear but is easier to handle.
My haematologist has done a B12 test so will be interesting to get results tomorrow.
