My husband was bedridden after a stroke.  Everything was tried – everything possible for bed sores.  He was a big man.  He had a special mattress.  He was in bed for five years after the stroke – in bed and in a wheelchair.  I purchased P.O.L. and it helped tremendously.  He died with no bed sores.  It was miraculous in what it did for my husband – it relieved the pain.
