My father 70 age diabetes patient have bed sore in hip area since last 3-4 months because of unconscious in hospital bed, we do not let him sit because of bed sore and we apply neomycin powder before as per doctor suggested but now we're applying health and coconut oil mixture. Bed sore is getting good but it's like stopped healing. The skin is not hard, if we let him sit of a minute then it gets damaged. So please help.
