I have lots of reusable GEL PAKS in the freezer. I lay one on the areas that are itching. Works great for me and once you buy a nice supply of them (Dollar Tree) you don't have anymore expense.
Let's see... I need 2 small ones to put in my arm pits and 4 larger ones to lay on my arms. I just have to remember to put them back in the freezer in the mornings 😋
I have been told by a hair dresser that "you better stop scratching your scalp...you will become bald in those areas" Well, I don't use her anymore.
Now, the lady that cuts my hair understands what is going on with my scalp sores....she has the same thing going on. Sure makes my time in her chair relaxing.
