That's interesting. I would think heat would make it worse but hey, it's worth a try. She has low iron so she's always cold and I feel bad telling her to keep her AC down so her apartment doesn't get warm. It seems like when she gets home or the least little warm, it is worse. But I will definitely tell her to try this and see what happens.
Thank you!

Hello, this will sound unconventional and it is and works, and often holds relief for many hours each time…

If I itch bad, I get my hair dryer on high/hot and zap the itchy spots.

I hold it there as long as I can then take it off then it’ll tingle sometimes likely the nerve stopping the itch in response to the heat.

It works. I do it as often as needed.
Then after or later in the day I’ll put on an unscented lotion over the spots I zapped to prevent dryness, etc.

Good luck :)

I am age 73 and have ET, not PMF. I have itching occasionally, not constantly. Sending sympathy to your mother and you. Products that help me: Aveeno Daily Moisturizing Body Wash in the shower and Aveeno Daily Moisturizing Body Lotion once I'm dry. Also, Eucerin Itch Soothing Cream and (the strongest but unpleasant smell) Aveeno Anti-Itch Concentrated Lotion. With doctor's approval I also have used Cortizone-10 anti-itch cream. Good luck!

Thank you Janice for this info. We've tried most of these and nothing seems to relieve her itching. It's the worst on her head, back and butt. I know it's something internal since we've tried so many of the "anti-itch, sensitive skin, free and clear" products. It's just horrible.
