I have been wondering if the pain in my side is related to gluten intolerance. I have been gluten free for just over two months and my health is much improved. However, I often get a pain on my left side above my waist. When it is bad, it circles around the left side of my back. It can be extremely painful. The odd thing is, once I eat a substantial meal it always gets better. If I allow myself to go without food, I feel the pain starting, and it will get worse until I eat. I know I am not the only one who gets this pain because others are reporting the same type of pain in the same place. I would think spleen because of where the pain is, but why does it go away when I eat? I will make an appointment with my doctor. Thank you for sharing your experiences. This is very helpful for me.
