  If you experience a rash or tickling sensation on your skin during treatment, it could be due to several reasons. First, the treatment time might be too long, so try doing the treatment once a day and shortening the duration. Second, the electrode may not be sticking well to the skin; ensure it is properly attached. Third, the electrode interface might be dirty or dry; clean it with a wet cotton cloth before use. Finally, you may be sensitive to the electrode. Check your allergy history, change the placement of the electrode, or shorten the treatment time. If your skin is over-sensitive, stop the treatment and consult a doctor.
