I had conjunctivitis 1 week ago and the symptoms have returned, what should I do?

One week ago (Saturday August 6) I had conjunctivitis (gift from my son) for which I completed the treatment on Friday (sterisporin) but the symptoms had already disappeared on Tuesday. Last night I woke up with my eyes irritated and very red, a bit stuck but without a green "crust". I thought it was a relapse until someone pointed out to me that the air conditioning in the hotel where we were staying was quite intense and that I had the air directly in my face the night before while trying to adjust it. I also had a dry throat and a blocked nose for 2 nights. My eyes are even more red than when I went to the pharmacist on August 6, tingling and burning. My vision was also disturbed/blurred for part of the day. Can air conditioning do this or is it probably a recurrence of conjunctivitis (no one in the house apparently has it yet). I do not take any medication on a regular basis, I am breastfeeding my 10 month old son.
