Frankly I'm not sure. You'll have to give me more details. Does it affect all your fingers? Both hands? What specifically "gives out"?
Do any movements of your neck affect the tingling and weakness in your arms?
It's not clear: was the thyroidectomy a month ago? If so you should certainly contact the surgeon.
Only one thing is going to change the misery in your life, Doreen. A complete change of lifestyle. Vegas wasn't built in a day, nor can you make these changes overnight. Start one by one with these:
Anti inflammatory omega 3
Broccoli osteoarthritis Olive garden nutrition
looks at the virtues of the Mediterranean diet. Chicken bones bouillon ...
proven at Harvard to be anti arthritic.
Add a steady supply of fruit and vegetables to your diet. Visit the fresh food market every week, it's here that you'll get the anti cancer and anti arthritis foods that your body is craving.
Do it bit by bit. But do it... and take a walk every day too.
I hope this has contributed.
