Conjunctivitis or Keratitis?

I wear contact lenses on a daily basis for around 8 - 10 hours a day. Yesterday I woke up with my right eye very itchy and could feel something in it, when I looked in the mirror I could see something that resembled my contact lens on the cornea. I knew I had definitely taken out my contact lens (i checked my lens case to be sure and they were definitely there.) Anyway I put a cotton wool pad rinsed in ice cold water which took the swelling and redness down slightly but I could still feel something in my eye. Today I went to see the optician and he said i have conjunctivitis and gave me Chlorophenicol eye drops and advised me not to wear my contacts for a week. I asked him if it could be a corneal ulcer and he said no it wasn't. Then later on in the day I had an appointment at my doctors for something else and while there my doctor couldn't help but had a look at my eye as it was slightly red at this point. The doctor says its keratitis and has given me Betnesol drops. Am so confused as to what my condition is and which medication I am supposed to be using. To make matters worse my opticians don't have a regular optician in, the earliest they will have an optician in will be Friday. Any advice much appreciated. Thanks in advance.
