Sweat and stump skin rash - Stump care

What appear to be sweat and hot conditions seem to cause my arm stump to become irritated and develop a mildly itching, red bumpy rash - similar to a baby butt rash or heat rash.

Proper stump care is key to controlling this. Also, check the water conditions.

So even after just an hour or so, my arm may be dripping wet. Many of you may be able to avoid that by having air condition surround them - but in our hot summers and no air conditioning, I am getting this almost daily.

Sometimes the rash gets more pronounced at the rim of the liner just below my elbow - sometimes the rash can cover the whole stump, even if only very mildly. Then it is time to act, act all the time, act fast, prevent. I take this very seriously as I don't want a serious itch or not be able to wear my arm.

Here is what I do about that (and a lot of research went into this):

  • Every 1-2 hours if possible, at least every 3-4 hours: Take off prosthesis and dry both the liner and the stump completely. It has to be a clean towel that I use and where necessary I make sure I have a towel with me.
  • Every evening: Wash stump and liner thoroughly - not just by rinsing, but by gently rubbing it - using skin-friendly neutral soap (such as pH 5.5 soap). No disinfection required as that could on the long run create other risks.
  • Every 1-2 days - if necessary more often - I apply a gentle amount of baby butt creme containing zinc-oxide on the whole stump to treat any existing or developing heat rash, and to impede the development of any new heat rash. In cooler weather I am able to do without baby butt creme for a week or even two. But preventive strikes have proven useful here.
  • Every evening, I put some soothing skin care on my stump. This can be (a) baby butt creme, (b) shea butter, (c) cocos oil / butter, (d) olive oil.
  • Once a week or so, in the shower, I use skin-friendly neutral soap and DIY olive oil salt scrub to very gently exfoliate and keep the skin supple.
  • A couple of times a week I air the skin and do not wear the prosthesis. Usually when I do not need the prosthetic function really badly.
  • Water: I use cold tap water. If I use warm water, I let the tap run for quite a while. Most houses have luke warm water sit in the tubes for hours and then, microbes grow. They are harmless for the most part but damaged or overused skin such as on the stump can suffer weird infections. More details here.
  • Treat eczema: I don't use corticosteroid cremes if possible. My doctor prescribed Protopic (R) containing Tacrolimus as active ingredient. Really neat stuff.
  • Silicone liner: Make sure to get a good fitting liner. Commercial products such as Ossur liners may not provide a good fit but instead cause eczema.
  • Friction reduction: By far the most important step to prevent rashes from occurring is wearing tubular gauze between silicone liner and the skin. That in essence solves the rash issue almost totally. When I wear tube gauze, it does not matter whether I wash the liner or stump - I just won't get a rash. The material is cotton and as it is a two-way stretch material, one needs to buy it slightly smaller than the limb width.

The underlying problem of rash initiation due to wrong socket or liner materials when wearing a prosthetic arm is also discussed in this article:
