Hi Chris - good to hear from you - college now, eh?
Anyway, about the eye - have you tried to use an allergy drop to get rid of the redness? Try this - it WIll get the red out if your eye got irritated from the shampoo.
If you have 'pinkeye' or conjunctivitis, you would be seeing ALOT of exudate (pus, etc),it could get to the point it would be difficult to open your eye - it would feel grainy, itchy, maybe even hurt a bit. 'Pink eye' is very contagious - I would imagine it could spread quickly in a dorm, etc, anywhere there's lots of people. Treatment includes an antibiotic eye ointment, also, changing your pillow case & towels daily, not touching your eye with your hands, frequent hand washing. Using a paper towel to open doors, etc. so as not to spread the infection - you should isolate yourself for a few days & use the antibiotic (prescribed) if you do have it.
Let's hope your eye got irritated from the shower.
Always good thoughts, Nancy
