Thank you for placing your query on Health Care Magic
What you describe appear to be a Bed Sore
. It appears that you been immobilized for a very long time. Bed sores develop at the spots where there is constant pressure along with perspiration.
1. If you are still bed ridden, use air mattresses which help to distribute the pressure points
2. Frequently change your posture or ask some one to help in doing so. Prefer sleeping on your flanks
2. Keep that area dry with powder
3. Applying spirit to the back helps toughen the skin and avoids bedsores
4. For the already developed bed sore, you need a surgeon/ plastic surgeon to debride it and do dressings. Once it heals it may require some sort of cover too.
5. Get cultures sent from the wound. It will dictate the antibiotics to be used.
6. Get your hemoglobin
and protein levels checked. They should kept in a normal range to promote healing.
Hope that helps
God bless you
