I spend most of my time in the Chronic Pain section of the Healing Well forum, but have started coming over here because of a recent diagnosis of Barrett's esophagus. So let me welcome you and also add you can post to more than one forum if you like (just like I'm doing).
I've had plantar fasciitis so I know what you're talking about. It reapears every so often especially as I'm adding a few extra pounds. Also have had failed lumbar fusion surgery. I do think you'll find a lot of us over on the Chronic Pain area have a lot in common with you. You can switch back and forth easily by using the "Forum Quick Jump" menu in the upper right hand corner. Best thing is to post and introduce yourself, especially the issues relevant to each forum (but many of us have multiple health issues - chronic illness tends to take its toll on the body!).
I'm still learning about the information in this section of the forum, so can't help answer those questions but you're welcome in the CP forum anytime.
