If you saw a person in a wheelchair or on crutches struggling to move, would you accuse them of milking it for attention? Not unless you were a truly malign, cold-hearted individual. If you saw a seemingly healthy person climbing out of a car that’s just been parked in a disabled parking spot, would you accost them and insist that they park elsewhere? Quite possibly, but before you do, it’s worth taking the time to consider whether that person actually does need the spot, even though they seem healthy.

There’s a little insight into the world of the hidden illness sufferer. Aside from the crippling physical pain they courageously endure on a daily basis, there’s also the frustration and torment of unsympathetic observers who take their exterior appearance at face value and believe that there’s nothing wrong. It doesn’t have to be a physical illness, either. Depression is also classified as a hidden illness, as it is a medical condition which might be highly concealed but has an enormously damaging impact on a person’s day-to-day life.

For people living with hidden illnesses, a basic degree of understanding and empathy from others is greatly appreciated. If you hear someone saying profusely that they’re feeling unwell, don’t just brush their words aside as the attention-seeking whines of a serial complainer. Ask them if there is anything you can do to make them feel a bit better. A person without a chronic illness just does not know the extent of the suffering of those with such illnesses.

This infographic from Burning Nights neatly summarises 10 of the most common hidden illnesses so that we can all obtain a small level of understanding. This include multiple sclerosis, rheumatoid arthritis, fibromyalgia, osteoarthritis, depression, Ehlers-Danlos syndrome, Lyme disease, Lupus and CRPS. Maybe the next time we see a seemingly healthy person occupying a handicapped parking space, we won’t be so hasty in our judgement.
