Hi all. I really dont know were to start. I have been supplementing b12 5000mcg for roughly 6mths. Initially after a few weeks I felt wonderful. A few mths ago I started to feel rather unwell again. Headache, fatigue and no interest in every day tasks. I kept taking the b12 and then I read that sometimes high b12 can cause low potassium. I started eating 2 bananas a day and noticed an improvement in symptoms. I had my b12 tested at this time and it was 2000. My tsh at this time was raised at 2.75 and was advised on this forum that it was too high but my doc is refusing to raise my thyroxcine the usual story.
I also am now experiencing lightheadedness, ringing in ears,fatigue and tingling and numbness in hands and feet. I have been supplementing iron, vitamin d and calcium as this was slightly low at last test. Vitamin d was 58 and ferretin 38 but since supplementing this could be higher.
I just dont know what symptoms are coming from what deficiency.
Do use think even though my b12 is high that it could stil be the problem or low potassium. Im so confused and cant get appt for bloods till after Easter. I know this could also be my tsh being too high.
