Unless you have a full range of natural movement, you will have your own individual trauma imprint. Created by the formation of physical restrictions within your body-wide web of connectives tissues as a response to inflammation, this trauma imprint is your record of the damage and stress your body has experienced.
The body's inflammatory processes are complex and can initiated by many things.
→ Injuries, accidents, abuse, surgery. Infections (bacterial, viral etc.). Stress, fear, the things that make us tense, flinch, freeze-up. Awkward positions, immobility, shocks, strains, exertions, slips, falls. The list goes on.
Anything that triggers inflammation will result in 'sticky' connective tissues, and, if not released through movement, these sticky tissues become 'stored trauma' and part of your individual trauma imprint.
Your unique trauma imprint is responsible for your particular collection of pain-related symptoms.

From a long list of symptoms (all with varying severity and time-scales) there are countless combinations that give you your individual group of clinical signs.
Signs and symptoms occur along damaged and restricted threads. These trends are what I believe are the basis of TCM. Physicians describing patterns observed over how many years? How many patients? I'd guess at many hundreds of years, thousands of patients...
Whatever your individual trauma imprint is, the fix is the same. Connect with your learn to heal yourself by developing your sense of Your body. Your pain. You can fix it.
