There are a number of different ways to sustain an injury. Micro and macro trauma are the two types of injuries an individual can sustain. Macro trauma is stepping of a curb and rolling your ankle. Micro trauma is from repetitive movements and positions causing stress to the tissues involved leading to small “micro” tears in muscle and connective tissue. You may not remember doing anything specific at one time to cause an injury; it may be due to an accumulation of small undetectable trauma which has resulted in the pain you are experiencing.
