Fibromyalgia is to be recognised by health professionals in Northern Ireland as a long-term condition.
People who suffer from it complain of aches all over the body, as well as profound fatigue.
Other symptoms include headaches, sleep deprivation and difficulty concentrating.
Despite the severity of symptoms, people living with the condition in NI have said their voices have gone unheard and their symptoms ignored.
After being inundated with complaints, the Patient and Client Council in Northern Ireland three years ago pressed the case for fibromyalgia to be recognised as a long-term condition.
Having interviewed sufferers and lobbied politicians and health professionals, dedicated services are to be established across the health trusts.
