Pain comes in many forms. Physical pain, emotional pain, pain from injury, or disease. You can’t always see the pain someone else suffers. But that doesn’t make it any less real.
Temporary physical pain that heals, can impact someone’s life for a short period. When the injury heals and the pain subsides, most people forget it happened and they’re ready to move on. But the long term effects will not be seen and can be life changing to the person who suffered the injury.
Constant chronic pain of the body, often can’t be seen either. But it’s often ignored by others who can’t understand the suffering because they can see its effects. That doesn’t make it any less real or life changing.
