Itchy Skin Cures

For decades, I have had periods of severe itching and I have tried everything to relieve it. Finally, by accident, I applied some white vinegar to an area for another purpose and found that the itching stopped there for at least 24 hours. Now before I take my regular evening shower, I take a white vinegar shower to stop the itching. I leave the vinegar there for several minutes before taking my regular shower with soap. After my regular shower most of the vinegar odor is gone. Anyway, what is a slight odor compared to severe itching?
