Hi. I'm online and happy to answer your question today.
No. There is no need to go to the ER.
You have already done the best treatment: Flushing your eye with a lot of water.
You eye will be just fine although it may feel like something is in it for the next 24 hours, sting and be a bit red.
At this point you should use artificial tears to soothe your eye as well as a cold compress to help it to feel better.
We have been experiencing problems with the chat system for the last few days. Our engineers are working on it. However, I'll switch over to the Q&A system. This system works a lot like 'text messaging' but an email is sent to each of us anytime something is posted to this thread. We can continue to work on your question there..... :)
Did you mean to say there is NO need to worry or there IS need to worry about my eye? And I may be misspeaking.....the doctor didn't actually say it was pink eye.....he actually is referring me to a opthamologist, but said to use these drops to see if it helped, which is does seem to. It's only been 24 hours but my eye seems to be getting better. I had a lot of redness and some crusting around my eye upon waking in the morning....not a lot of itching, which I know is classic pink eye. Any thoughts?
