Suggest Remedy For Severe Itching In Soles Of Hands And Feet

My daughter is 33 weeks pregnant and suffering with severe itching. The itching started only on soles of her hands and feet but at the moment it is itching allover. She says her skin is burning and it feels raw. I took her to the emergency unit and they did some urine and blood test! Her urea count is low 1.7(u), c- reactive prot high 14.2(u), total protein -s 59 low and albumin s 29(u) low. Then her ALK. Phosp.-s is 259(u) *High, alt (sgpt) 152(u) *high and AST (SGOT) 86(u) High. Our GP has given her several cortisone creams and they gave her another at the ER but she uses them within 2 days with no relief! She is using 50mg Attarax at night and 25mg during the day! She had 2 courses of antibiotics for an infection in the urine and is still has a milky urine. She is going to see a gynaecologist tomorrow. Can you tell us if there is any need to worry about cholestasis? She weighs 87kg and is 1.65 and is 21. Before pregnancy she had PCOS with insulin resistance. She used Androcur and Ginette.
