There are 2 different things going on and may or may not be related...
While I don't experience Raynaud's in my extremities, I suffered MIGHTILY on my nipples during the first few months of breastfeeding my first child. It gradually lessened on its own, but when I described it to my midwife while pregnant with my 2nd child, right away she told me what it was and what I could do for it. So, almost immediately following the birth of my daughter (wanted to see if it was going to be a problem again... it was), I did what she recommended, and I cannot sing its praises enough!!!! It worked!!
I don't know for sure if what worked for me will work for hands, but I took 250mg of B6 for 4 days, then a maintenance dose of 25mg per day for about 10 months until I decided to try without the maintenance dose, and by then, I was fine.
The joint pain may or may not be related to the Raynaud's. I have really bad joint pain at night on occasion, and I've found that I either didn't have enough water the day before, or I haven't had a chiropractic adjustment in more than a week. (I'd love to see my chiro every week, but I just can't afford it, so I go every 2) Increasing my fluid intake, seeing my chiro, and watching my sleep positions (including pillow!!!!) usually does the trick for me. But I really sympathize with you because there were nights I just couldn't sleep it hurt THAT BAD :(
