Hi Daphnee,
You just got a lot of great advice here from all these ladies & I think you should listen to it all...
While knitting a sweater for my husband last year I was in so much pain that I had to take off 5 or more days in a row from it. I finally saw my doctor for it & "joikingly" or not, I told him it was a "knitting injury". We laughed but it wasn't so far fetched.
It turned out to be both arthritis and tendonitis!! Wrists, hands & fingers... He put me on Daypro, an NSAID, which I also sometimes take for my fibromyalgia and my bad rotator cuff in my left shoulder. Also told me to use ice for 10 minutes & then soak it in hot water.
I also used those menthol pads under my knitting support gloves while I was knitting to keep things warm inside and even now I wear wrist warmers while knitting to help prevent it.
Yesterday I rubbed Mineral Ice on my right hand & wrist, which was sad since that "was" my good hand!
When it's really bad I do all of this plus I wear the wrist brace to keep it immobile. That's really the best thing for it until it heals.
Crochet is much easier on me than knitting but I do switch off now & then. I'm in my knitting mode right now. But you can crochet and knit with the brace on. Slower maybe, put you can do it. It keeps you from moving the wrist.
I "know how" to continental knit but I haven't practiced it enough to be comfortable with it yet. Just like when you first learn to knit...it takes practice in holding your yarn & fingers right, etc...
The computer mouse is really my worst enemy for my right hand & wrist. But I won't stop that either...Aren't we a stubborn bunch? LOL!
SOOO, listen to all the advice these ladies gave you & try the ice & then hot water soaks. Keep your hands & wrists as warm as you can 'while' knitting. (Maybe your kitty can help you there!) Get a "firm" brace to wear. If all this fails then you have no choice but to see your doctor...but I think you will see results in a few days.
You should lay off the knitting until you try all this first. Even Aspirin is an anti-inflammatory. Just don't over-do it. And I swear by those menthol pads!!
I hope you will be feeling better in no time!!! Please keep us posted on your progress & what you did to improve.
