But if the pressure is removed allowing blood to circulate and toxic by-products to be flushed, initial damage may be reversed. But irreversible damage can occur if pressure isn't removed. Experts say such damage can happen in one to six hours if conditions are right. Pressure is transmitted in a cone shape with the point of cone at the skin surface and the base overlying the bone. Any part of the body is vulnerable to pressure sores but most sores are likely over bony projections.
Good nutrition can help prevent the occurrence of pressure sores.
I also have a formula that I have developed to treat and heal pressure sores, if you would like the information I would be happy to forward it to you.
