Thank you Marimac. I am so busy some days that I barely think about what's causing the pain (in regards to whether eating certain foods are part of the problem). However, I do agree with you that I should give it more thought. I have read that a no-starch or low-starch diet is better for those with ankylosing spondylitis. One of my friends, who is an herbalist, told me that vegetables (and there may be fruits as well) from the nightshade family aggravate arthritis. Tomatoes are in the nightshade family.

I was hoping that this testing would be more definitive. It's possible that my insurance company would cover more of the medication if I had a diagnosis. Indocin takes care of most of my pain.

You have some great suggestions. Thank you!!!
