Just out of curiosity, were you ever evaluated for CRPS (Complex Regional Pain Syndrome)? Other than your symptoms being bilateral (less common with CRPS), you fit the profile well.
If you’re unfamiliar, here is the link and excerpt from the NIH fact sheet for CRPS:
What causes CRPS?
It is unclear why some individuals develop CRPS while others with similar trauma do not. In more than 90 percent of cases, the condition is triggered by a clear history of trauma or injury. The most common triggers are fractures, sprains/strains, soft tissue injury (such as burns, cuts, or bruises), limb immobilization (such as being in a cast), surgery, or even minor medical procedures such as needle stick. CRPS represents an abnormal response that magnifies the effects of the injury. Some people respond excessively to a trigger that causes no problem for other people, such as what is observed in people who have food allergies.
