Top 10 Thigh Bruise Causes

  1. 1.Viral (Norovirus) Infection

    Noroviruses are a group of related viruses that leads to nausea, vomiting, diarrhea, and cramps. These viruses cause gastroenteritis, an inflammation of the stomach and intestines. When the diarrhea and/or vomiting is severe, dehydration can occur. Symptoms of dehydration include a dry mouth, dizziness, urinating less frequently and dark urine.

    You can safely treat this condition at home. Make sure you drink plenty of water and fluids (Gatorade, Pediatlyte) to replace what is lost with diarrhea. If symptoms of dehydration occur or you are unable to keep down any liquids, seek care at your primary care physician or an urgent care.

  2. 2.Thigh Bruise

    A bruise is the damage of the blood vessels that return blood to the heart (the capillaries and veins), which causes pooling of the blood. This explains the blue/purple color of most bruises.

    You can treat this at home with R.I.C.E - rest (exercise as tolerated), ice (10-20 minutes at a time), compression (this is pretty optional), and elevation (put your feet up to help blood flow back to the heart using gravity).

  3. 3.Femoral Stress Fracture

    A femoral stress fracture is a small crack in the thigh bone (femur). These fractures are most often a result of overuse and are commonly seen with an increase in activity. Stress fractures of the thigh bone are much less common than those of the shin bone (tibia), but nonetheless do occur in high-risk groups such as athletes and military recruits.

    You need to get your injury checked by a physician, sometimes a MRI scan is needed to confirm the diagnosis. It may be helpful to consult with a physical therapist as well. The treatment for a stress fracture involves avoiding repeated stress on the leg, which means cutting down on high-intensity activity. Exercise that puts less repeated stress on the leg, such as cycling or swimming, is recommended.

  6. 6.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:

  7. 7.Tension Headache (Previously Undiagnosed)

    Tension-type headaches are the most common type of headache. It is pain or discomfort in the head and/or neck. It is often accompanied by muscle tightness in these areas. This condition can occur as little as once a year but as often as more than 15 days per month (chronic). The cause of tension-type headaches is not clear.

    You can safely treat this condition on your own. Tension-type headaches are diagnosed purely by your symptoms. Medications like over-the-counter pain killers (e.g., ibuprofen or Tylenol) may help. Be cautious with dosage and how often these are used. If these headaches become more chronic in nature, you should visit your primary care physician, who will evaluate your symptoms and may be able to prescribe a stronger medications.

    Top Symptoms:
    history of headaches, nausea or vomiting, loss of appetite, moderate headache, mild headache

  8. 8.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.

    Rare
    Top Symptoms:
    fatigue, irritability, anxiety, difficulty concentrating, trouble sleeping
    Urgency:
    Primary care doctor

  10. 10.Collapsed Lung (Pneumothorax)

    A collapsed lung happens when air enters the pleural space, the area between the lung and the chest wall. If it is a total collapse, it is called pneumothorax.

    You should go to the ER immediately as a pneumothorax can de-stabilize your ability to breathe and your blood flow from the heart. Diagnosis involves an immediate chest x-ray. Confirmation leads to different decisions on whether to treat the pneumothorax or let it heal naturally under doctor supervision.
