I live in Chicago area. I’ve had only 2 injections in two months since getting diagnosed with b12. My level was 112 at diagnosis. My symptoms went from numbing tingling, to burning almost frostbite feeling in my foot... most of this is better but then I had 3 weeks straight of nausea and headache, thinking I had a tumor ( went for brain mri and clear)... now nausea has turned to more of a burning feeling in my stomach when I eat anything. Had an endoscopy and they said normal. I’ve struggled with my young 6 year old son Having a cancerous brain tumor last year ( he is ok now by some miracle). The day after his last mri this all started for me...of course everyone thinks it’s anxiety but I know my body. I am paranoid this burning stomach could be something serious. Has anyone experienced this with b12? I am driving my husband and family crazy with all of these thoughts and imaging tests, etc.... anyone with insight to the burning stomach thank you in advance!!!i am also going to find a doctor that will give me more frequent injections... thanks all!
