Many of us will sadly have suffered from a painful health condition at some point in our lives, with some people affected every day by problems that may well be invisible to the rest of us.
While there are countless conditions that can affect our daily lives, some are more debilitating than others, and the NHS has shared a list of what are believed to be the twenty most painful. While there are several things on the list that you'd expect to see, such as heart attacks, broken bones or a slipped disc, some are much lesser known.
For example, many people may not have heard of cluster headaches - a rare and painful condition that takes the top spot - as well as things like complex regional pain syndrome, trigeminal neuralgia, and fibromyalgia. Here is the full list of the 20 'most painful' conditions, what causes them and their most common symptoms according to the NHS, InYourArea reports.
