I am 33 years old and ever since the age of ten I've had a strange issue that couldn't be diagnosed. Every time I drank apple juice over the years my back would hurt so badly afterward that I have been afraid to even attempt it over the last ten years or so. Other things started to have he same effect about ten years ago. I also cannot drink fruit punch or eat apples. This evening I cut up a watermelon for my kids and it looked so good that I decided to have some myself and about half an hour later, here I sit in bed with excruciating back pain that does not seem to involve my stomach. It wraps around my rib cage but is most painful in my mid to upper back. I would love to figure this out as I am actually afraid of what certain foods can do to me. Any ideas would be greatly appreciated! Thanks, Jennifer L. Smith
