After typhoid 5 vaccines and medication for around 13 days, my mother started getting red itchy rashes with swelling(mostly on back), only at night, starts from 2:00am and disappears around 5:00 am. This allergy started after typhoid medications, happening from 2 weeks, initially 1-2 rashes. Increased from last 2 days, now she is unable to sleep at that time due to itching. Does this allergy generally happen after typhoid treatment? How to reduce or control it?
