Can you tell if someone it in pain or hurt just by looking at them?
Be cautious what you judge based on what you see. Just because someone has a diagnosis that isn't "Scary" like:
Cancer
Stroke
Heart Attack
Broken bones
Visible Wounds or Scars
Missing limbs
What happens if you see someone that looks perfectly healthy but they are dealing with chronic hidden pain that you can't see.
Infections: Mono, Lime's Disease...
Auto-Immune conditions: Chron's/ Colitis (ulcers), ...
Brain: Migraines, Concussion, Function loss or slow processing, ...
Wide spread pain: Fibromyalgia, Chronic fatigue syndrome, MS...
Mental/Emotional: Depression, Bipolar, Anxiety, OCD, Grief....
Be care what you thing someone should be capable of. What should hurt or shouldn't .. etc. Be Kind
Here is a personal example, I don't mean to post this for the sake of getting sympathy. I post this to prove it's possible to not realize what some one is going through...
