The story is a fantasy, but the setting has medical technology roughly equivalent to that of mid-17th Century Western medicine. Suturing and disinfecting practices are a bit more advanced than in that time period, but no invasive elective surgery. A 15 year old boy has suffered an anterior dislocation of his non-dominant shoulder three times over the course of a month.
1) What permanent damage can be suffered after repeated shoulder dislocation at a young age? I've read 10-15 different pages on "shoulder dislocation," tried Googling "dislocated shoulder permanent damage," and read the Wikipedia page on shoulder dislocation. All the pages I've found are very high-level and mention only that permanent damage may result, that the joint is destabilized, and that surgery may be needed. Since shoulder surgery isn't an option for my character, I need to find out a) What parts of the joint become damaged, b) What this means for his mobility and his health, c) whether this will cause chronic pain for the rest of his life, and if so, d) what that pain will be like (constant, only with certain movements, dull, sharp, etc.).
2) If he's badly damaged the joint, would he still be suffering reduced mobility, weakness, and significant pain, 2-3 weeks after his second dislocation?
