"My son's dignity was stripped away"

My son was brought into ED. He suffers with MS, is immobile and bed bound, reliant on two people to assist for full care as he has no use of his upper or lower limbs. He was left on a hard trolley with sides down falling off the bed, left with no water for 24hrs in scorching heat, left in soaking wet urine pad for 24hrs and not washed. Spoke to staff who advised they thought he was independent, which I found incredible as he needs two staff for full care. This was Hairmyres emergency department, no care, compassion or communication, my son's dignity was stripped away and I would not like this to happen to anyone else.
