Living with chronic pain — from lower back problems to fibromyalgia, arthritis or migraines — is a daily struggle, made even more difficult when sufferers feel misunderstood by the people around them.

And sadly, chronic pain is incredibly common.

Forty million adults suffer from severe levels of pain, though less regularly, than the chronic sufferers.
