My father has recently passed and I am currently sitting shiva. However, I am in my 5th day of not bathing and my skin is very itchy and making it hard to sleep. Am I permissible to shower?

Regarding your question, since you are very itchy, washing the area that itches is permitted. You can wash it with soap or whatever is needed to get rid of the itching.
