Hello ma'am, sorry to read about your troubles!
The pictures you show show a lot of scratching, which can make the situation worse.
For now, I recommend using a fragrance-free moisturizer such as Cerave, Cutibase, Glaxal Base, Aveeno or others as often as needed during the day, whenever the need to scratch arises
Use a fragrance-free soap such as Dove, and after the shower avoid rubbing the skin vigorously to dry it; instead, lightly pat it dry to leave a thin layer of moisture and apply moisturizer within 5 minutes of leaving the shower.
If you are able, I suggest trying to identify a cause, whether it is a food or a product such as a new soap or detergent.
If it persists or gets worse, you will need to see a doctor.
Sincerely
Tom Samaha, pharmacist
