Top 10 Flexible Joints Causes

  1. 1.Hypothyroidism

    Hypothyroidism occurs when the thyroid, a butterfly-shaped organ inside the neck, no longer produces adequate levels of hormones. Thyroid hormones are essential for many bodily functions including breathing, heart rate, and metabolism.

    You should visit your primary care physician. Hypothyroidism is a complex condition that is usually treated with hormone replacement therapy.

    Rarity:
    Rare
    Top Symptoms:
    fatigue, depressed mood, difficulty concentrating, weight gain, muscle aches
    Urgency:
    Primary care doctor
  2. 2.Fibromyalgia

    Fibromyalgia is a disorder that causes widespread pain, tenderness, and fatigue.

    Fibromyalgia is treated symptomatically. Medication, therapy, and stress reduction may reduce symptoms.

    Rarity:
    Common
    Top Symptoms:
    fatigue, anxiety, trouble sleeping, depressed mood, headache
    Symptoms that always occur with fibromyalgia:
    hidden: arthralgias or myalgias
    Urgency:
    Primary care doctor
  3. 3.Lyme Disease

    Lyme Disease is a bacterial infection caused by the bite of a tick, which needs to latch on for a few days to transmit the bacteria. This infection can affect the skin, but more dangerously, the nervous system.

    You should see your doctor in the next few days to discuss symptoms and get treatment.

    Rarity:
    Rare
    Top Symptoms:
    fatigue, headache, muscle aches, irritability, loss of appetite
    Urgency:
    Primary care doctor
  4. 4.Graves' Disease

    The thyroid gland is a butterfly-shaped organ inside the neck that is responsible for making thyroid hormones. These hormones control important body functions, such as heart rate and the rate at which the body turns food into energy. In Grave's disease, the immune system malfunctions and drives the thyroid to produce excessive amounts of hormones, leading to symptoms such as trouble sleeping, irritability and nervousness, heat sensitivity, hand tremors, and weight loss.

    You should visit your primary care physician to get your blood tested. Grave's disease is a complex condition that is managed with prescription antithyroid medications, as well as surgery in rare cases.

    Rarity:
    Rare
    Top Symptoms:
    fatigue, irritability, anxiety, difficulty concentrating, trouble sleeping
    Urgency:
    Primary care doctor
  5. 5.Chronic Low Back Pain of No Specific Origin

    A precise anatomical cause for low back pain can only be identified in 20 percent of cases. The rest of the time, the specific cause of the pain is unknown, and is likely due to strain on the bones and muscles of the back from heavy lifting, prolong sitting, or bad posture. Chronic low back pain is characteristic of back pain lasting longer than 12 weeks.

    For most people, back pain goes away within a few weeks. Because your back pain is lasting longer, you should make an appointment with a physician. You might find it harder to recover and might need additional treatment such as a program of back exercises. If the pain is not too severe, you can safely manage the pain at home with over-the-counter pain medication such as ibuprofen (Advil) and acetominophen (Tylenol). It is also recommended to stay active and carry on with the things you usually do as much as possible, to help you recover faster. Sitting or lying still for long periods can actually make the pain worse. Your joints may become stiff which will make it harder and more painful to move your back.

    Rarity:
    Common
    Top Symptoms:
    lower back pain, unintentional weight loss, fever, back pain that shoots to the butt, involuntary defecation
    Symptoms that always occur with chronic low back pain of no specific origin:
    lower back pain
    Symptoms that never occur with chronic low back pain of no specific origin:
    thigh numbness, buttocks numbness, lower back pain from an injury
    Urgency:
    Primary care doctor

  6. 6.Rotator Cuff Tendonitis

    Impingement syndrome is a common shoulder condition seen in aging adults. The tendons of rotator cuff muscles, whose action is to rotate the arm such such as during a tennis swing, pass in a narrow space between two bones in the shoulder. When the space becomes too narrow, which can happen as a result of an overuse injury, pain may develop as the tendons rub against the bones.

    You should visit your primary care physician who will coordinate care with a muscle and bone specialist (orthopedic surgeon). Treatments for impingement syndrome involve rest, over-the-counter pain medication, steroid injections, physical therapy, and surgery in rare, serious cases.

    Rarity:
    Common
    Top Symptoms:
    pain in one shoulder, dull, achy shoulder pain, shoulder pain that gets worse at night, difficulty moving the shoulder, shoulder pain from overuse
    Symptoms that always occur with rotator cuff tendonitis:
    pain in one shoulder
    Urgency:
    Primary care doctor
  7. 7.Overactive Thyroid

    The thyroid is a butterfly-shaped gland in the neck, just above your collarbone. It is one of your endocrine glands, which make hormones. Thyroid glands control how fast one burns calories and how fast the heart beats. If the thyroid is too active, it makes more thyroid hormones than the body needs. This is called hyperthyroidism.

    You should visit your primary care physician, who might take a blood test to measure your levels of thyroid hormone. The test will tell the doctor whether a referral to an endocrinologist is useful. Treatment plans would likely be set by the specialist and include drugs to reduce your thyroid activation.

    Rarity:
    Uncommon
    Top Symptoms:
    fatigue, anxiety, depressed mood, irritability, trouble sleeping
    Urgency:
    Primary care doctor
  8. 8.Stress - Induced Cardiomyopathy

    In this recently recognized heart problem, extreme emotional stress can lead to severe (but often short-term) heart muscle failure. Broken heart syndrome is also called stress-induced cardiomyopathy.

    You should visit your primary care physician within the next 24 hours. Your doctor will likely prescribe heart medications to reduce the workload on the heart while you recover.

    Rarity:
    Rare
    Top Symptoms:
    shortness of breath, racing heart beat, deep chest pain, behind the breast bone, excessive sweating, muscle aches
    Urgency:
    Primary care doctor
  9. 9.Organophosphate Poisoning

    Organophosphates are a compound used in insecticides and herbicides that can cause severe, sometimes life-threatening effects in injested or inhaled by humans. The use of organophosphates is currently being phased out in the United States, but thousands of exposures still occur every year.

    You need medication that is only available at the Emergency Department. Call an ambulance now.

    Rarity:
    Rare
    Top Symptoms:
    nausea, headache, diarrhea, abdominal cramps (stomach cramps), vomiting
    Urgency:
    Emergency medical service
  10. 10.Osteogenic Sarcoma

    Osteogenic sarcoma (osteosarcoma) is a cancer that starts in the bone, and usually affects the ends of the bone where new tissue forms at a growth plate. It is the most common cancerous bone tumor in young people, with the average age at diagnosis being 15 years. Pain in the bone is the most commonly reported symptom.

    You should visit your primary care physician who will be able to coordinate your care with a cancer specialist (oncologist). This condition is treated with chemotherapy and surgery. Unfortunately, surgery may involve amputation of the entire limb.

    Rarity:
    Rare
    Top Symptoms:
    spontaneous bone pain, swollen shin, lower leg bump, upper leg bump
    Symptoms that always occur with osteogenic sarcoma:
    spontaneous bone pain
    Urgency:
    Primary care doctor
