But now suddenly after taking covid vaccine..after 20-30 days of taking vaccine I am having hives,uteceria all over the body and high itching very bad one..for one week it's was horrible then it's reduce, itching is less but still keep coming and going and suddenly acne and pimple also start increasing.. So what to do??

Now what should I do should, should I take the 2 nd dose or not?? And why this happening ,a sin my case environment is also change but it's was always ..
