How long does B12 stay in the system for?
I had my b12 tested about 6 months ago, results came back a low-normal. Prior to the test though, for a week or two I was taking B12 strips that disolve on the tounge. Could this have flawed my tests?
Lately again, I've been getting pins and needles like mad, usually after quick motions, or workouts, sometimes just random. They happen all over my body, from my head to my toes. These can be painful enough for me to yell out. The p&n is usually followed by itchiness all over. I had an incident at work about two weeks ago were I was quite dizzy, with no explination, almost falling twice during this few hour time period. I also had the pins and needles. Later on that same night, my left knee became swollen and imflammed, it felt like it was going to hyper-extend when I would walk. Also, just the other day I felt like I was going to faint from laughing (wasn't a laugh attack or anything).
My p&n started out like they are now, they eventually turned to massive, completely random shots on every single part of my body that would cause my body to clench and squeeze from the pain. These only last for a few seconds and mostly happened lying in bed at night. I would also yell out when these happened, once waking my parents up.
My cardio is quite bad for the size of myself and body fat % in my opinion. I've noticed it's tired me out before my muscles do while working out.
Sound like possible low b12?
I also have slight social anxiety, slight depression and feelings of being lost.
In the past i've also had some unusual, paranoid thoughts, not beliefs. I still do somewhat I guess it depends on the day, it seems to come and go like the depression and anxiety but still I live a normal life.
I'm a fit 17 year old.
I've also had some involuntary movements of my arms, legs or head. I've come to realize that this is usually just a nervous twitch.. but it happens to me sitting at the computer, alone and not anxious at all. Usually my legs.
My hands can be very shaky also... people have pointed this out to me before..
I also have problem with my speech the last 6 months or so... I slur, stumble, mumble my words when talking and it's really been bothering me of late.. Could be the 5-6 hours ive only been getting on school night though im not sure. Never had a speech impediment or lyspe etc..
I keep remembering little stuff that's been bothering me for the while, some of it may be totally irrelevant.
Note:I also posted this in a Vitamin B12 deffincey thread, any help greatly appreciated!
