Do acupuncture bands prevent performing minor ablution and ghusl?
If it is not possible to remove and insert the needles or the plasters of the acupuncture during the acupuncture treatment, or if it causes great difficulties, they do not prevent one from performing ablution or ghusl as long as they are needed. In this case, the rulings on masah (wiping) over bandage are applied.
