Mom's not getting any better. Any advice?

Its going to be trial and elimination I suspect Pasport - what has the doc said about washing. Even if you use the same soap you have for years it doesn't mean that those fiendish manufacturers haven't added something into the mix that wasn't there before or that your Mum hasn't suddenly developed an intolerance to it. When it comes to drying I know a lot of people use hairdryers rather than actual towels to dry the irritated area. Your doc might recommend using aqueous cream to wash her too. Its a really wonderful cream you put it on like a cream and wash it off like you would a soap - do remember to ask them though

Thank you all for your help my moms doctor has now told us that we can not put any of our own cream on her and just the antebotic cream I think I will have to go and see her doctor i do live in England so I'll just keep trying to get some help

Mum gets the odd rash nothing like you're describing Passport but when she gets them I use something called aqueous cream or aveena both of which I know you can get in US

I would wonder about detergent as well, and especially if those toxic dryer sheets are used. From what I've read those dryer sheets are loaded with chemicals.

You might ask if anyone has yet taken a swab of the rash and had it analyzed to determine more about the rash.

Other irritating things are synthetic fabrics. If she's not wearing natural clothes (pure cottons and flannels) you might try switching to them, especially for her underwear.

Has the doctor recommended trying Benadryl or Claritin? They're pretty benign as far as interactions go, and may help relieve her symptoms if it's an allergic reaction.

Ok. Without straying above my pay grade, I'd check the obvious things like are her bed linen and underclothing being carefully laundered (no detergent residues left from inadequate rinsing or anything like that), is anyone using over-scented wipes or cleansers on her? It could be that there has been a recent change of products or personnel, or it could be that your mother's skin has been weakened by a chronic condition; it could be any number of things; but clearly if your mother has been cared for satisfactorily for some years at her nursing home it isn't any major flaw in their standards, so that's something to be grateful for.

The other thing that helped my itchy mother was silk underwear - you can get silk jersey at a reasonable price, and silk being hypoallergenic it doesn't irritate the skin and cause contact dermatitis so readily. The trouble with post-stroke weakness, as you know, is that the person is left less mobile, and the skin gets sweaty and sore where anything is constantly against it. But since this is a recent problem then there must be a new factor - hope you manage to track it down successfully.

He rash is on her arms and on her stomach under her arms

Where is the rash?

That must be awful for her. I can relate to your wanting to get her help. I suppose you could take her out to a dermatologist if her doctor isn't able to stop the itching. However, my husband went through a series of dr appointments trying to stop a rash that spread all over his arms and hands and back. He was told it was dormant eczema that he had probably had all his life. He has really suffered with it. It seems to go in cycles. He had a biopsy and that was the best they could come up with. This from a top rated dermatologist. I've decided that rashes are a real mystery in many cases. So many factors to consider. Diet, laundry detergent, medication side affects and everything you come in contact with. The fact that she can't scratch is a small blessing as that usually makes a rash worse. Recently one of my elders was told not to use lotions for an itch but to use creams or ointments. Dr said lotions contained water and that made the skin dryer. With her I have to watch or she will use the cream too often. Some of the stronger ones can thin the skin. Ask her dr what he will try next as the current treatment isn't giving her relief from the itching. The soap used for bathing can sometimes irritate or calm the skin. Some over the counter creams work better for relieving an itch. You might ask at your pharmacy and then discuss with her dr. Hopefully she will get relief soon. I know it wouldn't be easy to take her out of her care facility for treatment so hopefully her dr will keep trying for a solution. Perhaps someone on this site will have a better answer.
