A Few Days Ago, I Was Out At Night And

A few days ago, I was out at night and noticed that around the street lights I was seeing rainbows. This never happened to me before. For a few days prior to this, I was having shortness of breath. It was nothing painful, just difficult to take a deep breath. A few days later, I ended up in the emergency room, with severe stomach pain, which happens quite often with me as I have had my gallbladder removed and if I eat something that disagrees with me, it is very painful. In addition, I have neuropathy in my feet and have been diagnosed with epilepsy since becoming pregnant with my daughter over 19 years ago. In the emergency room, they did blood and urine tests and gave me a cat scan. They found nothing, but I feel that there is still something wrong with me as I have digestive issues quite often. Any ideas?
