My optometrist told me to always be aware of any redness, swelling, sty type inflammation and so on because he said these can be one more Crohn's symptom and they can be quite serious. I'd never had any troubles. Now all of a sudden in the past few months I'm seeing these things occur often, maybe every couple of weeks. Does anyone else suffer with these? They will hang around for a few days and go away on their own, but they are a little scary.
