Why do I feel pain even when I am not injured?
Some of the reasons why you feel pain even though you are not injured are fear, stress, neglect, abuse, trauma, emotional discomfort, etc.
Any health-related symptom is basically caused either by tissue damage or nerve pathways. Nerve pathways can cause real and severe symptoms. Pain is a nerve pathway created by experiencing repeated events of fear, stress, neglect, abuse, etc. and can be activated by re-experiencing the same emotions of fear, stress, and other negative emotions.
Pain pathways can be turned off by acquiring knowledge, power in your social environment, and confidence even if it may be only to accomplish your basic routines.
Psychological trauma and physical injury create an identical pathway
The emotional discomfort experienced in childhood, caused by abuse, divorce, neglect, etc., create pathways of negative emotions that we feel as danger or fear. And if ulterior stresses occur, new pathways will occur concomitantly. And even later in life, there might be a car accident that would trigger the fear pathways that are already sensitive. And new symptoms may occur, such as anxiety, depression, fatigue and so on. Living in this pattern will cause the nerve pathways to create intense pain.
