I have been self injecting b12 since last August.... With very good results. I have never made a full week before symptoms return so have been injecting several times a week. I read a post on the thyroid forum the other day about a correlation between supplementing b12 and folic acid and cancer.
Reading this really freaked me out. I'm normally quite grounded but this information just sent me in a spin. I am now scared to continue supplementing ..... Last injection was Tuesday and today I saw the return of some symptoms....pains in my wrists and hands, tingling and numbness in my fingers, painful feet, very loud tinnitus and very lethargic. I'm so confused. Common sense tells me to continue with the b12 but I'm really scared.
Also, why do I need to inject so often? Literally 5 days without injecting and I feel unwell.
Can someone shed any light on this claim that high supplementing of b12 can cause cancer?
I'm usually very level headed but I really feel like I've dived down a rabbit hole and can't get out!!
Hope someone can help
Thanks in advance
