I have some kind of skin allergy which results in red patches randomly all over body. In morning i can see those patches however till night it is less. Can it be possible that due to Vit
B12 injections, I am having this allergy? Because it never happened with me earlier. After certain period from which i had completed this course of
Vitamin B12 injection, I have observed this issue. However i felt much relief after taking antihistamines but den doc reduced the dose & again i took inj as i had not suspected allergy from B12 & again after one day red patches increased in large amount all over body.
