A Few Months Ago I Had Horribly Red Eyes And

A few months ago I had horribly red eyes and was told it was likely allergic conjunctivitis and that I had lots of scarring on my eyes from previous infections - none of which had caused me any discomfort or that I'd even noticed. I had oftaquix for a few weeks and it cleared my eyes right up and then I was given steroid drops for the scarring for one week. The redness came back and doesn't seem to be linked to me using contact lenses again. I have some oftaquix left, should I use this to clear it up again or does it sound like something more serious and worth seeing someone about in person?
