Well here's what happened to me.
1. had problems w/ hands while taking classes one of which was typing/keyboarding.
2. Went to ortho, had test for carpal tunnel and it said yes. Ortho says you need surgery, yada, yada, yada.
3. I said no (to much to go into) Did go up for prayer at church.
4. Got pair of those velcro braces and began to wear them to bed. (you get used to it.) Things got better.
5. Did some work (using my hands of course) things got real bad,fingers cripple up,hands hurt real bad.
6. Went to ortho, had another test, no carpal tunnel, "Chronic tendenitis". (glad I didn't have surgery).
7. Still wear braces to bed and at other times on occasion.
8. I have a wagon to drag water to my coop and any other stuff, feed, which I break down into cat litter jugs for a manageable weight. I use gallon milk jugs and fill the waterers at the coop. Only have two though.
So I suggest you wear the braces and modify everything you can. Avoid lifting or doing anything you can that will cause problems. Modify, modify, modify. Figure out ways to do what you need to.
My hands still hurt but not too bad. I just take it easy and breaks. My wife drives most of the time.
Break down heavy items in to managable sizes. I can't shovel snow so I have a big electric start mower and snow blower. I swear by cordless anything. Drill, saws, what ever I can get. Work in short periods take lots of breaks. Devise a managable routine.
Get a wagon or a powered cart. (They do have them by the way)
