I was given antibiotic for a urine infection they found blood I take for 3 days but my eye is now bothering me could it be sideeffect of anti_?

Eye pain. You should revised the list of adverse events in the package inset but may be a secondary efect not nessessarly a bad one. Discontinuation of the medication is the first step and call your doctor office if you suspected a secondary effect like that.
Not likely. You may have reiter's syndrome. This has eye, urination issues, and joint pain. Please see your ophthalmologist for further evaluation.
