Been Having Stomach Problems With Change In Bowels For Last

been having stomach problems with change in bowels for last year. dr says its IBS with constipation. as of the last couple months I have had trouble swallowing, ive also had unbearable itching on abdomen but no rash or dry skin, my eyes have started to yellow and they are very sore and very sensitive to light. I squint a lot and my vision has become more and more blurry. could you please give me some ideas. Thanks
