Dear maxkiplin,
I would recommend that he seek thecare of an eyeMD to determine the cause of the swelling and symptoms. IF it is viral, antibiotics will not help; however, other drops such as nonsteroidal antiinflammatories may help comfort.

The GP's are not going to be able to have a firm grip on treating this and some of the meds they prescribe could actually make it worse. He, of course, should see an ophthalmologist and it may well be that a combination of treatments may be needed including drops, ointment, oral pills sometimes. Sometimes just stopping the wrong antibiotic or offending agent can make a big difference. So I understand your concern, you just need to have him see a good ophthalmologist, perhaps even the one that saw him last time and helped him get better. Often if a treatment worked once it may help the next time.
