For the last few months, my eyes (especially my right eye) itches, feels like there is something inside. But now its worse. the irritation is more intense. I ve been using tears natural and even though i feel better when i do, problem stays there. Went to the doctor and game me dispersadron for infection but for some reason i feel its something else, cause my eye is not red or anthing.Also i must mention that i ve been using cocaine (three - four ) times per month, and i really got worried if this has something to do with it.
