I have hand, arm and neck problems, too and I feel your pain!
Here's a copy of a post I made a few weeks ago. Maybe it will help you!
I learned Portuguese knitting--VERY EASY and GREAT for those with hand problems!
I've been an English knitter for a long time, and developed carpal tunnel and arthritis in the past year. :wall: I've tried learning Continental knitting, but it made the arthritis worse, so bagged that idea. Last Saturday, however, some of my friends on any sock KAL suggested Turkish or Portuguese knitting and linked a YouTube video. Well, that got me searching for more tutorial-type videos. These are the ones that helped me.
In this one, she explains a yarn holder. Good for me, since neck problems prevent me from putting the yarn around my neck. I use a safety-pin type stitch holder and put it through a buttonhole (or my bra strap, if there's no buttonhole:aww:).
This one shows the basic knit stitch. She goes slowly enough to actually tell what she's doing. Take note that you DO cross your right needle over the FRONT of the left needle and then flip the yarn over it with your thumb.
This one shows the purl stitch, which is actually EASIER than the knit stich!
And this one shows ribbing.
Here's casting on, but it's in Portuguese! I'm sure you can use whatever cast on works for you!
You're never too old to learn new techniques! If nothing else, this gives you an alternative method for when your hands get tired.
I had to give up knitting for awhile, but I'm back at it. HOPEFULLY after a rest, you'll be able to find a way that works for you!:hug:
