How long can one wear this. My dad has to undergo Postrate gland operation, but Spinal MRI for neurosurgeon says, he has compression at C6 area. Now doctors are unsure after postrate gland operation, things will be normal. If this has to be tried if in worst circumstances .. Please can you tell me if this can be worn for long long time with no Infection. With Foley's he had twice serious infection. We are really scared.
