Thanks to journeythru, Marlene J, linzsey, Katie, and WarriorGal for your responses to my post on episcleritis.  Your experiences and insight are very helpful to me, too.  Great discussion!  

On one other new thing, today, I received my results from an upper GI scope and colonoscopy I had two weeks ago (my first).  I have been having non-stop diarrhea and cramping for almost a year now.  Come to find out, I have microscopic colitis, which would cause those symptoms, and which can be caused by medications.  It is quite possible that my Enbrel Rx may be causing this for me, because a year is about how long I have been taking Enbrel (maybe longer).  But, I’m not about to go off of Enbrel, as it is helping my RA immensely.  I did start to take some over the counter digestive enzymes, and my GI doc told me today that that is fine.  They have really helped my symptoms a lot.  He also recommended probiotics and a fiber supplement.  He also wrote a prescription for me, specifically for the colitis, in case I need it, which is reassuring.  I just wanted to let you know that these medications we take for RA can be the cause of some other very real and difficult symptoms that might only be found under a microscope.
