May mistook allergy for bacterial pinkeye used sulfacetamide for 7 days. off of it for a week now and my eye is only red when i pull on the bottom should i start a round of polymyxin? or could taking more antibiotics make it worse? am i contagious?

Not enough information provided beside 'red eye.' Given the absence of typical symptoms of bacterial conjunctivitis, i.e., noticeable eye discharge, you might have an allergic conjunctivitis, not a contagious nor treatable condition with antibiotics.

Most cases of conjunctivitis are allergic or viral not bacterial The antibiotics you’re taking only work on bacteria. Most virus infections are self limited. Allergies respond to topical medication such as Zaditor. If it’s not resolving or you’re having blurred vision, you need to see you an ophthalmologist
