2. Venereal diseases
Venereal diseases, including syphilis were widely prevalent in the middle ages due to lack of antibiotics. Instead, the cure involved some rather painful procedures where the physician would insert catheters made of metal into the bladder. Similarly, in advanced cases of hemorrhoids, the physicians were likely to make use of stones and irons in quasi-surgical procedures.
1. Medieval enema
One of the most common way to inject medicine in the patients during the medieval ages was through the anus. It involved the use of a tube with a piston like apparatus attached to the other end. Medicinal water was poured through a funnel to the other end and pumped into the colon region. This procedure, known as clysters, was especially favored by the royalty in France.
