Arthritis Research Campaign | Fibromyalgia: "Sometimes tiredness (fatigue) can be the most severe aspect of fibromyalgia. There may be overall tiredness and lack of energy, or muscular fatigue and loss of stamina. Either way, it can be difficult to climb the stairs, do the household chores, go shopping or go to work. Becoming less fit makes matters worse. Waking in the morning feeling unrefreshed is common.
Less frequent but still troublesome symptoms include:
poor circulation tingling, numbness or swelling
of the hands and feet
headache, irritability or feeling low or weepy
forgetfulness or poor concentration
feeling an urgent need to pass water
irritable bowels (diarrhoea and abdominal pain).
Of course symptoms like these can have other causes, and your doctor can help decide whether any further tests or advice are needed. The severity of the symptoms and the effects of fibromyalgia can vary considerably, and this range of severity can cause problems in diagnosing the condition and lead to varying medical opinions. A particular feature of fibromyalgia is the need to have the symptoms recognised and to be taken seriously."
