I was diagnosed as b12 deficient about 4years ago. It was immediately assumed by my doctor/nurses that I had PA but my symptoms do not match the majority of symptoms that bloggers record on this site.
However, my experience has been over this time, that after the 12 weekly injection, my signature symptom returns after 6/8 weeks and it begins with 5/7 occurrences on the first day then, over 5/6 day’s it reduces then ceases.
After the last three injections covering 36 weeks, I have had my signature symptom return very soon after the injection.
My latest injection was Wednesday at 9:50 and by 12:10 my signature symptom reoccurred but this time only once. The same occurred on Thursday - only once and today, so far, only once.
Originally, I had a whole cluster of symptoms which ceased very soon after my injection regime began but the signature symptom continued. It is:
1 I become semi conscious
2 tinnitus occurs - like bad reception on a radio
3 a sense of euphoria and a dream like occurrence which seems to make sense while it’s happening but makes no sense afterwards.The sequence lasts for about 10 seconds.
The tinnitushas not recurred for over two years; the dream like sequence has largely dissipated and when it does happen it is much weaker.
I am simply left with the semi conscious state which occurs out of the blue. If I am listening to someone or reading, suddenly nothing makes sense and it takes several minutes to recover understanding.
My memory is affected temporarily especially sequencing eg something that occurred the previous day would become come - was it yesterday or was it earlier etc.
I must say, I do feel that my condition has improved dramatically since my diagnosis and treatment.
I can articulate whereas before speech fluency was severely affected; my aphasia is still apparent but incidents are less common; I rarely feel exhausted; blurred vision has ceased etc.
But what is it about the injection that is causing the symptoms to occur or is this just a coincidence?
I have yet to discover, of course, whether, as before, the symptoms will recur in 6/8 weeks time.
