Is rubing alcohol or nonsente hand sanetiser on my ringworm before putting my medicated medicine good or bad?

Immaterial: It will make little or no difference, since the alcohol evaporates rapidly and will not do any damage to the antifungal action of your medicated ointment, and eliminating a few bacteria with the alcohol will neither improve or deteriorate the dermatophytic fungus causing your ringworm.

Irrelevant: Alcohol sanitizer will not affect anti-fungal treatment. If the anti-fungal treatment does not resolve the matter in a week or so, it would be prudent to see a doctor for a proper diagnosis and treatment.
