Thank you so much for sharing this! The timing is perfect for me as well.
I have RA, I'm 46 and have had it over 25 years. I had to stop working and go on disability a couple of years ago. It's pretty depressing after working since I was 14. But I'm getting through it. I just wanted to give a little background.
Two weeks ago I started the C25K program. I love it. I have never run in my life, and I ran for 9 minutes three times this week. If you are not familiar with the program, they have a website and an iPhone app which is what I use. They train you to go from the couch to a 5k by running and walking intervals. So if you are like me and have no idea how to start running, this program is awesome.
Like you, I hurt every day. But the running does not hurt much more than my normal daily pain, at least not yet. I'm sure an injury or flare will change that, so I'm being very careful. The first day I actually made it through the 31 minutes of walking and running, I cried like a baby. Just to be able to run again feels amazing.
For those of you who need help starting so you know how far and how often to try running to avoid injury, check out C25K: http://www.c25k.com/. It's no exaggeration to say it has changed my life.
