My Mom of 87 years just got out of the hospital suffering from a severe UTI and Bladder infection along with a yeast infection, under the breasts and also inside the crack of her buttocks (both sides) are blisters and reddness. Sent her home with some cream and powder, but has not helped. The sores are very painful needless to say especially in a sitting position. She tries to shift side to side, but still is very uncomfortable. They almost look like ulcers. I have been bathing the sores in luke warm water and applying the creams from the hospital, but I think the creams are making them worse. Any suggestions? Thank you.
