I'm pretty certain I have arthritus. I understand its pretty common in CF, so I guess I pulled the short straw and got yet another ailment. My joints often ache, and about every other month or so my wrist hurts where I must wear a carpall tunnel sleeve, as I can't lift with it. So my question is how do you go about treating it? I have taken about 400mg of Iubrofen, but it reads on the back that you shouldn't take it for more then 10 days, what then?
