rosacea
"I've had what they said was blepharitis all of my life.  It started spreading under a lower eyelid so I went to a dermatologist (after spending hundreds at an opthamologist and him putting me on several antibiotics and eyedrops).  She put me on Oracea and it made it so much better;  even the bloodshot, scratchy eyes.  The only drawback is that it has given me severe heartburn, which I've never had before.  "
