Hi. Thanks for your query. Noted the history and understood your concerns. Surely yes, you need immediate attention of an Ophthalmologist for the floaters in eyes. Lymphocytic colitis is an inflammation of the colon and the causes can be varied from inflammatory causes and infective in some. Hence it is necessary to know the cause which can be found by the following ways: Detailed history, clinical evaluation, examination. Tests of stool for three consecutive days. Tests of the blood for CBC, thyroid and liver functions. A course of an antibiotic, metronidazole and probiotics may help. In cases of inflammation a course of oral steroids may help. Skin rashes can be a part of the immunity complexes. Hence I would advise you to consult a Gastroenterologist for further evaluation and proper management. Stress and anxiety also have a role in enhancing the problems and hence should be under control. Foods and beverages to be found out as to which suit you and which enhance or instigate the problems and stop such immediately.
