Hi. My wife is 7 months pregnant. She is 29 year old. From the past 20 days, she is facing continuous itching on the whole body. Mainly in her palm and her sole, which is irreparable and continuous. She is unable to get her sleep because of it. She was taking calcium and iron medication, which she has stopped now. Also have tried allegra and itching lotion, which were of least use. Kindly guide.
