1. Myofascial Pain Syndromes (MPS)
FM should be distinguished from Myofascial Pain Syndrome (MPS). Both show increased sensitivity on finger palpation of certain points, but in MPS there are trigger points (instead of tenderpoints) that give pain in a further removed area of the body and localized muscle impairment. Unlike FM, trigger points will decrease in local therapy. Trigger points are painful hardening in the muscles that no longer relax. A trigger point can cause restriction of movement, stiffness, loss of strength, and pain symptoms. A trigger point is not the same as muscle cramps. You speak of cramping when a complete muscle contracts violently. A trigger point is a cramping of a small part of a muscle. A muscle cramp can relax in minutes. Trigger points do not relax as quickly for physiological reasons and can persist for a long time and constantly cause pain symptoms. Trigger points can cause headaches, neck and jaw pain, lower back pain, tennis arm and other complaints. They can be the cause of joint pain, such as the shoulder, wrist, hip, knee and ankle, which are often mistaken for arthritis, tendonitis, sinusitis, osteoarthritis and numbness in the hands and feet. Even fibromyalgia can have its origins in trigger points.
2. FM and Chronic Fatigue Syndrome (CFS)
Although there are similar symptoms between fibromyalgia and CFS, they differ from each other in a number of points. CVS is particularly characterized by chronic fatigue along with difficulty in concentration, decreased expression and coordination disorders. The criteria for CVS were prepared by members of the American Centers for Disease Control and Prevention (CDC) and the National Institutes of Health. The CDC criteria are based entirely on symptoms and on the exclusion of chronic active organic and psychiatric disorders that result in chronic fatigue.
3. Irritable Bowel
In the colon there are nerves that cause the muscles of the intestine to contract. With irritable bowel, the muscles will cause severe abdominal cramps and diarrhea due to nerve hypersensitivity. In addition to diarrhea, there may be periods of constipation. In the absence of Crohn's disease (chronic inflammation of the small and/or large intestine) and Ulcerative colitis (chronic inflammation of the large intestine mucosa), it is necessary to check whether the patient has no hypersensitivity to certain food components.
4. Irritable Bladder
This is characterized by a painful, burning sensation during urination. Patients experience the same symptoms as with urinary tract infection caused by bacteria in the bladder or urethra. However, FM does not find bacteria if urine is analysed under a microscope. If urine has a foul smell, blood or fever occurs, there is a high risk of infection that needs immediate treatment.
5. Raynaud syndrome
Some fibromyalgia patients experience poor blood flow in the peripheral parts of the body, characterized by contractions of the small arteries in the hands and feet. Affected areas can turn red, white or blue (or all three at the same time) and feel cold.
6. Memory impairment
FM patients often experience impaired concentration, forget certain things,. Some claim that these memory impairments are caused by abnormality in part of the brain, others are more likely to think of oxygen deficiency.
7. Vertigo and ear and hearing problems
In addition to the other complaints, patients may experience vertigo and hearing problems. Vertigo is understood to be twisted dizziness. People get the feeling that everything is revolving around, when it's not the case. Tinnitus is also a common burden. By tinnitus one means buzzing, twitched, crackling,.
8. Hypoglycaemia
This means low blood glucose. The symptoms that occur with hypoglycemia are different and vary in nature: headache, dizziness, irritability, fatigue, depression, nervousness, memory and concentration problems, palpitations, trembling hands, sweat attacks, a feeling of impending mischief, cramps legs, stiffened or tingling hands and/or feet, flushing, feeling of impotence and sometimes fainting.

9. Mitral valve prolapse
In the heart muscle there are four heart valves: two in the right heart half and two in the left heart half. The mitral valve is located in the left heart half and controls the supply of blood from the lungs to the left ventricle. The mitral valve is located between the left front chamber and the left ventricle. When contraction of the anterior chamber, the mitral valve opens and allows blood flow to the left ventricle. With each contraction of the left ventricle, the mitral valve closes and does not allow backflow of blood to the left front chamber. Mitral valve prolapse (PMK) in which the valve bends abnormally occurs in approximately 3 to 5% of the population and approximately 70% of FM patients. PMK causes headache, fatigue, spastic colon and a change in connective tissue.
10.Premenstrual Syndrome
This syndrome occurs only in women who are still menstruating. It occurs just before menstruation and causes both physical and psychological complaints. The disorders encountered are headache, insomnia, back pain, abdominal pain,. They are so fierce that they cannot be held out and lead to bed. These women also experience confusion and dejection.
11.Crohn's Disease
Crohn's disease is a chronic inflammation of the small and/or large intestine, which often rises for the first time between the 15th and 30th years of life. Complaints most common in Crohn's disease include:
Loose stools or diarrhea: the inflamed bowel cannot absorb enough fluid.
Slimming, anemia, or growth retardation: the inflamed intestine does not absorb certain nutrients that may cause deficiencies in the body. As a result, fatigue also develops.
Blood loss: inflammation causes injuries in the intestine, which can cause blood loss in the stool.
Constriction (stenosis): when inflammation is very severe (acute phase) at a certain site, a narrowing in the intestine may develop. Unfortunately, there is no simple test to determine Crohn's disease yet.
12.Hypothyroidism
The thyroid hormones, and in particular T3, control the rate at which the various cellular combustion processes go. If there is too little thyroid hormone available, these processes are too slow, is there too much than they go too fast. The thyroid gland can be compared to the car's accelerator. The thyroid gland can make the body processes run faster or slower, it is controlled by the pituitary gland and indirectly by the hypothalamus.
13.The Lyme Disease
Lyme disease, also known as tick bite disease, Lyme disease, or Borreliosis, is transmitted almost in all cases by the bite of a tick, which is infected with the bacterium Borrelia burgdorferi. The consequences of an untreated infection include chronic pain and fatigue complaints. The symptoms of Lyme disease develop slowly and not in everyone in the same way. Within days to months (usually within three weeks), a red spot may develop around the tick bite site that is slowly increasing. The red spot disappears by itself. You may also feel flu after a few weeks, with fever, headaches, muscle pain and fatigue. The flu and red spot can occur independently of each other. Weeks to months after the tick bite, the following symptoms may occur: pain, loss of strength, or numb and tingling sensation in the arm, leg or trunk. Months to years after a tick bite, swelling and pain in one or more joints may develop, especially in the arms and legs. Also, skin disorders may occur.
14.Postpolio syndrome (PPS)
FM patients who have experienced child paralysis show this syndrome. Some complaints that occur with PPS belong to FM. PPS could be another cause of FM. PPS causes a reduction in motor functions by dying off the motor nerve cells that send messages from the spinal cord to the muscles. The nerve cells that remain have to take over the task which causes nerve cells to die faster. This will weaken the body, even if the virus is gone for a long time.
15.Spasmophilia or autonomic dysfunction
The symptoms of spasmophilia or autonomic dysfunction usually have to do with muscle overirritability. The pattern of complaints can be very diverse: hyperventilation, muscle cramps, fatigue, anxiety, insomnia, dizziness, shortness of breath, chest pain, abdominal pain, belching, cold hands/feet, unexplained rash. . For spasmophilia, there is no ready-made remedy. Because the muscles are hurting, one will be less (daring) moving, causing one to become 'deconditioned' and making rehabilitation more difficult. Therefore, try to stay in condition by moving sufficiently - safely - and by a good movement pattern (moving but not stressed). Hiking and cycling - sometimes swimming - are ideal. Always move at your own pace and avoid sports with peak efforts such as tennis, football, squash.
16. Adrenal insufficiency
Due to poor functioning of the adrenal cortex, insufficient aldosterone and cortisol are produced. Aldosterone is especially important for our body's salt and water balance and blood pressure. It ensures the exchange of sodium and potassium ions in the kidneys and thus regulates the amount of water and salts in our system. Cortisol is important for energy and bone metabolism and for converting signals on neurological and immunological levels. Cortisol deficiency may also cause too low glucose levels. Cortisol is especially important in stress and effort. The condition is caused by disorders in the immune system, where the body starts to defend against the adrenal cortex. This condition is not curable, but can be perfectly controlled by giving certain hormones.
