try some allergy eye drops you can get them at wal mart. if its not better by the next morning he does need to go to the doctor.
10 yr. old son--blood-shot eye (right eye on outside) for almost 3 weeks. no other issues. is it time to see the doctor? . don't want to go overboard about it but i don't want to find out there is damage and i didn't do anything about it. after two weeks it was getting much better almost disappeared. but has come back with a vengeance. looks worse than it did when it first began. it did come on gradually. he says it does not hurt or burn. takes zyrtec daily for seasonal allergies. he started the end of april and usually takes it until october. he says he has not hit himself. should he see an eye doctor?
