Sudden itching

Suddenly, only one eye from a week ago

It was insanely itchy.

I just rubbed it without thinking.

The white membrane inside the eye is swollen.

I kept feeling a foreign body sensation in my eye..

Usually, after this, it all subsides once you sleep.

I woke up in the morning and suddenly went crazy again.

It itched...ㅠ so I thought I shouldn't rub it.

I tried putting in artificial tears first, but it just didn't work at all.

I also included the allergy medication.

Usually, it's okay when you put allergy medicine in.

My son's itching hasn't subsided.

I have the antibiotic ointment I was using, so I'll apply that.

After about 10 minutes outside, it settled down.

And then sometimes it still itches...

I used to put medicine in my son's food every time.

Is it okay now that the itch has subsided?

I'm not sure if it's okay to continue taking this medication..
