Physicians were trained in medical schools and universities during the Late Middle Ages. In fact the medical schools had existed since the Early Middle Ages or earlier. Their medical practice consisted of much more than a study of leeches, and the education of a physician took a number of years.
Up to 10 years.
Leeches can live up to 6 months without feeding, but they typically feed every few weeks. Some species of leeches can live up to 20 years in the right conditions.
Much more primitive than it is today!
People can live up to 120 years with today's advancment in medical technology.
Saline solution sprayed onto the affected area causes the Leech to recoil and it can simply be pulled away. Leeches were used in medical science for years and if for any reason they couldn't be removed then they would have never have used them.
Leeches are used in modern medicine to help with blood circulation in procedures like skin grafts and reattachments of fingers. They secrete compounds that have blood-thinning, anti-inflammatory, and pain-relieving effects, which can aid in healing processes.

It takes about 11 years after high school, 4 years of collage, 4 years of medical school, and 3 years of medical training.
Leeches are a type of segmented worm known as annelids, and they are believed to have evolved around 300 million years ago during the Carboniferous period. They have undergone various evolutionary adaptations over time to survive in different aquatic environments.
Typically, there are four premed years followed by four medical school years for a total of eight years.
