Hi all yesterday I got a 3rd opinion at a neurologist for neurological issues that I’ve had for a long while now. I was diagnosed with PA in 2016 I had to argue with my hemotologist for a long time for injections which I was able to get in August of 2017. The reason for this is because I live in the US and they think the B12 pills are adequate. I’ve had a lot of the classic neurological symptoms of MS and my 2nd opinion doctor thought I may have had it as well but no lesions showed on brain scan. These are rapidly declining vision, tingling in feet, twitching in left eye (for a year now nonstop), lightheadedness and balance issues, and very poor memory with extreme fatigue. Quick side question — is rapidly declining vision a symptom of PA? Anyway, my 3rd opinion yesterday at a very reputable place thinks it is all permenant damage from my PA. I’ve been SI since August of 2017 once a month until about 6 months ago I bought more B12 so I could SI every few days. Nothing has helped my symptoms and I’m wondering how much damage I actually have from this condition or if I still have another undiagnosed condition. I can’t imagine walking around with very unsteady gait (so much so that I need a cane or walker) for the rest of my life, I just turned 33. I’m unable to work and do my daily obligations because of this. Are there any tests that I could ask for that may check for permanent damage? Any advice would be appreciated. Thanks!
