I also wanted to welcome you to the chronic pain forum of Healing Well. It's the best support group on the internet, IMHO! We're not doctors, but share a lot of our experiences and just from reading your initial post I know you'll have much in common with many here.
Like you (and many others) it seems so much else gets worse after CP enters our lives, and I also have recently be diagnosed with Barrett's esophagus with mild dysplasia, which is precancerous. I never had chronic acid reflux problem except over this past year. Was very healthy until I took a bad fall and then life unravels, like you know.
A few things about the forum. One, there are other forums on Healing Well that address other conditions (I post sometimes to the GERD forum for the Barrett's). You can post to more than one, and it's easy if you just use the Quick Jump menu at the top. Also, you can edit your own post (add more, delte parts, etc.) by clicking on the pencil icon in the upper right hand corner. If you click on the 'X" you can delete your entire post, but only moderators can edit others' posts. If you've been reading here awhile, you know we have several wonderful moderators here - Chutz, Lindaloo, White Beard, Straydog, HelloKitty and Stella (have I missed anyone?). They're volunteers and suffer from the same problems we all have, but they can be helpful, plus aid in keeping us all playing within the rules of the forum. It's a good idea to read through them, so you'll see that discussing politics isn't permitted, so you don't have to share that, and may even want to delete it. Keeping away from topics like politics and religion helps keep arguments down, IMHO, and I think Peter, who is the administrator and started Healing Well, did a brilliant job the way he structured this.
So anyway, others will be along to add more.
