At age 70 my father was bitten by a dog, and subsequently developed a leg ulcer that never healed. He had access to free health care, and was able to see an MD, or an RN, once a week, and every week, but the MDs were very little or no help.

He didn't have any other health issues.

They did dress that wound every week, however that ulcer was still an open wound at age 80 when he passed away.
