You’ve likely watched a driver maneuver into a handicapped spot … then get out of the car with seemingly no difficulty. The absence of a visible injury typically earns a disapproving stare, but there might be more to the story than meets the eye.

People often judge an illness’s severity by its outward symptoms or the assistive equipment it requires, like a wheelchair or cane. However, according to the Invisible Disabilities Association, 74% of Americans who live with a severe disability or illness do not use any form of assistive equipment. 

Complex Regional Pain Syndrome, or CRPS, is one condition that goes unseen. Considered an “invisible illness,” CRPS sufferers may look completely healthy on the outside. 

Understanding an invisible illness can be tricky but speaking to someone experiencing one can be even more challenging. At Pain Specialists of Charleston, we believe in not only managing and alleviating pain but also providing knowledge of pain that is not always evident. 

Keep reading to learn more about invisible illnesses, and to find out how to better understand someone suffering from pain you cannot see. 

What is an Invisible Illness? 

An invisible illness is defined as a physical, mental, or neurological condition that is not visible to others. For those suffering from an invisible illness, finding the correct diagnosis can be difficult. Many patients must undergo a process of elimination after reporting their symptoms for a diagnosis to be made. 

In addition to CRPS, these conditions are often classified as invisible illnesses: 

  • Rheumatoid arthritis 
  • Fibromyalgia
  • Lupus
  • Migraine headaches

Many invisible illnesses share common symptoms like fatigue, headaches, and body pain – which cannot be tested for. CRPS signs and symptoms may include: 

  • Continuous burning or throbbing pain 
  • Sensitivity to touch or cold 
  • Muscle spasms and weakness 
  • Limited or decreased mobility in affected body part

Because symptoms may change over time and vary from person to person, CRPS can be very difficult to diagnose. Plus, symptoms may spread from the original source to elsewhere in the body. 

Impacts of Living with an Invisible Illness 

Living with an illness that is difficult to diagnose or has subjective symptoms can make each day a struggle. Because an accurate diagnosis requires more than a simple blood test, many sufferers are left with debilitating pain. Bouts of depression and anxiety may follow, along with feelings of isolation.

It can be very difficult for others to understand exactly what CRPS patients are going through and why they may seem “different” than before.

Finding the Right Words: Speaking to Someone with an Invisible Illness 


People who are close to someone with CRPS or other invisible illnesses may struggle to find the right words to say. Showing compassion and comfort is key, so be sure to avoid saying the following: 

  1. “You have what? I’ve never heard of it.”
  2. “You need to exercise more.”
  3. “Aren’t you feeling better yet?”
  4. “Maybe an antidepressant would help.”
  5. “But you look just fine.” or “You don’t look sick.”
  6. “You are taking too much medicine.”
  7. “You need to change your diet.”
  8. “It’s all in your head.”
  9. “Losing weight might help.”
  10. “If you just had a more positive attitude.”

This list, courtesy of Molly’s Fund, an organization that raises funds and awareness for Lupus, encourages swapping the phrases above for these: 

  1. “How are you doing today?”
  2. “Is there anything I can do to make things easier?”
  3. “I am here for you, whatever you need.”
  4. “It must be very difficult to have a disease where you feel so awful on the inside but it doesn’t show on the outside.”
  5. “I am so sorry that you are going through this.”
  6. “I wish I could take your pain away.”
  7. “I hope you are feeling better soon.”
  8. “I will keep you in my thoughts and prayers.”
  9. “I may not completely understand your disease or what you’re going through, but I would like to.”
  10. “I am so sorry I judged you before understanding your disease.”
