Hi Cassee,
Sorry to read that you broke your knuckle, but great that you won't be forcing yourself to have a perfect home until it heals.I have had Fibro all of my adult life, and I adapted and learned many tricks about cleaning house.
1. I bought a wheeled stool like a Dr. stool. I sweep and mop while scooting on that, I have a taller stool for doing dishes and sitting by the stove to cook, sitting at the counter to chop veggies and prep food.
2. I learned that my jobs don't have to be done religiously every few days. I lowered my standard of perfection some. Things get done when I am able. It's not worth pushing so hard that I make myself sick. I was OCD about my house before I got sick but I had to calm down.
3. I clean out as many items in my house as possible. The less I have, the less I have to take care of. Simplify your life, minimize. Why have 1 gadget to cut eggs, one to cut strawberries, one to slice tomatoes etc. when a knife can do them all?
4. I started my children helping me very young and it turned out a great thing, because when they grew up, they were teaching their own friends how to do simple household chores and meals. Most had no clue how to clean anything or make a simple meal alone.
5. I have hired a housekeeper now and then, especially to help with Christmas decorating, wrapping, cleaning, and undecorating, and I have one now, just twice a month for the harder jobs. It amazes me how easily and quickly she does things that would take me days.
5. Take breaks. I have to work for 10 minutes, then rest, then work 10-20 more minutes, then rest. Take each job and do it in little chunks.
6. Get the lightest tools you can. I love my Vileda mopper. It's like a Wet Jet, but the pad is washable and I can use my own cleaning solution rather than buying theirs all the time. Vileda has about 8 types of mops but I found mine to be the easiest. Aluminum brooms are lighter than wood handled ones. Get a lighter vacuum for little jobs, even a manual carpet sweeper, then keep the big vacuum for when it all needs a thorough vacuuming.I don't do anything on my knees. I do it while sitting. I use a long handled reacher to get things that are on the floor or out of reach or rolled under the bed. If I HAVE to kneel to get it, I roll up a towels to kneel on, but that doesn't happen very often now that my kids are grown. I vacuum while sitting as much as possible.
7. I have learned that strong chemical cleaners make me sicker, so I have gone back to old fashioned cleaners like baking soda (kills germs), vinegar (cleans glass and chrome), hydrogen peroxide (disinfecting for viruses, infections) and they are much cheaper. I like my pine-sol (so many scents to choose from) but I just use a capful for a huge amount of water.
8. I hire help for the yard and I have a relative help take out the garbage. Don't know if you need that yet. I also have lupus and heart failure so I can't make the trek to the back alley.But it is often worth it to hire a teen girl or college girl to do a lot of the jobs for $10-15 an hour. Don't feel guilty about hiring help. Delegation is a great way to be more productive. Healthy people even hire help, so why not you? Even if just once in a while.
Necessity is the mother of invention. I hope more ideas come to you so you can adjust to your "new normal" and make things easier.
