I’m not sure whether others have experienced this or this is just a freak coincidence.
Before I developed B12 deficiency I got tennis elbow and had no problems with the neoprene arm band.
Now, after B12 deficiency diagnosis, I have just got tennis elbow yet again. Now however, I cannot wear the neoprene arm band without developing severe itching and skin eruptions.
Is allergy a common feature of B12 deficiency?
P.S. I am being successfully treated.
