Ever since she had taken the Pfizer Corona Vaccine, every times she ate a lot of fruits and vegetables she seemed to be getting this rash all over her body that won't go away. It was scary, she was scratching and itching, starting to get worried because she was bleeding everywhere. She was afraid she may eat and get anaphylaxis. The patient had Hydroxyzine and asked if she can take Hydroxyzine for the allergic reaction. She wondered if her allergy to Benadryl could be part of the allergic reaction she was having.
