Hello. I am asking for my mother. She is 76 years old, 4 ft. 10 in. and weights73 pounds. She has advanced osteoporosis, arthritis and sculosis. She also has hyper thyroid disease and was positive for herpes but its levels are under control. She has been experiencing severe itching mostly on her back, arms, back of neck and chest but also it starting to go to part of her legs. We didn t get a straight answer from her doctor when we asked if it could be her thyroid disease and medication. She is going to the dermatologist next week is there a product to relief her itching you would recommend?
