Hi foni1. I note that you are B12 deficient and on injections. I've been convinced that I'm B12 deficient due to my symptoms but my results came back normal. Unfortunately, I've read (on nhs info amongst others) that the test is not always reliable as only test total B12 levels rather than just active. I therefore started self injecting and indeed, I do seem to feel better afterwards, but it doesn't seem to last.
I am perimenopausal confirmed by blood test and I am finding hard to know whether my symptoms are that of the perimenopause or the B12 deficiency and I am finding it very frustrating. I decided to give hrt a go and I'm now on my 4th week. So far, I haven't really felt a real benefit. Like you, I struggle with tingling and pins and needles in my hands and feet and terrible tinnitus, which is worse when the tingling is. What is so confusing is that some days I feel dreadful and then suddenly, out of the blue, I'll have a better day without symptoms to hit be again with a hammer the next. Even today, I woke up feeling best I had for a long time, no symptoms and some little energy I normally never get on Saturday mornings and I felt great until an hour ago and out of the blue, the tinnitus, tingling and muscle aching is back with that feeling of drain.
I have no idea if it's the perimenopause, the B12 or something else although nothing else picked up and I wish I knew. I don't suffer from hot flushes or even night sweats, everything is more of a neurological nature. I'm giving hrt 3 months to see if it makes a difference. If it doesn't, I'll just stop and up the injections. Like you, I'm desperate to feel like me again and feel totally loss.
