Shower Chair
A plastic chair or stool so you can sit down in the shower is easily obtained from pretty much anywhere. You can get "official" shower chairs and stools from a medical supply store or rehabilitation centre, but these cost a lot and really aren't that different from any plastic chair. Metal is okay as long as it's painted or sealed so it won't rust. Make sure you chair or stool has rubber stoppers on all its feet so it doesn't slip in the shower, too.
A shower chair is useful even if you can physically stand in the shower. After all, wouldn't you rather use all that energy for something fun, instead of for standing up?
Electric toothbrush
Any electric toothbrush from your local shop will do, my dentist informs me. Electric toothbrushes are a life-saver if your arms get tired quickly or you have muscle weakness and pain.
My dentist, after hearing my problems with tooth cleaning, also prescribed a special high-fluoride toothpaste which helps prevent cavities if you're too sick to brush often. This might be worth asking a dentist about if you're in a similar situation.
Pill Box
A pill box marked off with sections for each day of the week and each time of the day you need to take pills can be invaluable. These are especially useful if you suffer from brain-fog and sometimes can't remember if you've taken pills. They also mean that for most of the week you can just tip out the right pills and take them without having to remember which ones to count out or how many.
I suggest you keep a written down list of what pills you take when, to aid in refilling the container. And a hot tip: If you have to take a powder or liquid or something else that you can't put into the pill-box, put a button in the appropriate box to alert you of, "something special". Just make sure you don't swallow the button!
Heating Pad
A heating pad, hot water bottle, hot pack or wheat bag can all help with those sore tired muscles. They can also help with morning stiffness, if used along with judicious stretches.
Also good for keeping warm on cold nights!
Walking Stick
No, not to lean on!
Well, not just for leaning on. Depending on how your arms are it may well be useful to lean on. The most important thing a walking stick can do is let people know you're disabled! People with CFS and/or Fibromyalgia usually look pretty healthy, and it can be difficult to explain why a healthy-looking twenty-something isn't getting up to offer their train seat to the mother with an armful of parcels ... but if you have your trusty walking stick, you can just wave it around a bit and people understand at least that there's "something wrong" with you.
Having Fibromyalgia/CFS is a pain in more places than one, but having an invisible disability doesn't exempt you from finding gadgets useful.
