How do pressure sores start? There are many ways. For wheelchair users sores are most common on the buttocks. Sitting too long without taking breaks can cause them. So can "bad" transfers, where the skin might be affected by an abrasion or more severe impact when moving to or from the wheelchair. Diabetics can have decreased blood flow to their extremities, which can make breakdown possible in the feet and legs. Bedridden people can develop sores on their feet or buttocks from laying in one position too long, or from laying on mattresses that don't provide good skin protection. Every one's skin becomes thinner as we age, too, making us more susceptible to breakdown.
In my case, I'm pretty sure that a rash on my rear end started the process. I hate to admit it, but I was at fault. I picked at the skin that was peeling away, and I believe I picked some live skin away with some dead skin that was flaking off. Something as simple as that started the whole process...
