Please don't feel guilty for being pain free. I've been in a lot of pain for a long time. Was initially misdiagnosed several years ago, and only just learned what's really going on. But it does my heart good to know that there are some of us with this disease who have achieved "pain free".. 
I pray that it stays that way for you. I, like so many others am soooo tired of being sick & in pain! Of missing out on life because of the pain...of not getting to go for Sunday drives with my hubby to get away from the rat race for a couple hours, cause the drive hurts too much! I've only just begun the doc thing, and I'm sick of that too...so please, those not in any pain, please just be grateful for the reprieve, and get some enjoyment from life while the gettin's good!!!! Bless you all!
