After a slightly rough few weeks fighting a parotid infection, my private doctor advised a second PIN infusion as well as the B12 methyl infusion which I requested and off I went and had both last weekend. We did have a little debate about how much MethylB12 to put in the infusion: his view was that 10mg would be sufficient, which is what went in.
I had my doubts about whether the pins and needles in my left leg was down to B12 deficiency as most of my other symptoms seem to have cleared up after self injecting for the last four months. My expectations were that any excess would be flushed out so I half expected my urine to turn slightly pink at some point over the weekend but it didn't. Either there wasn't enough B12 in the infusion or I've excreted the excess some other way. The numb area seems to have become smaller, but I can't be certain that's not slightly wishful thinking.
I wondered whether anyone else who's had a B12 infusion had pink pee afterwards?
