  2. 2.Concussion Not Needing Imaging

    A traumatic brain injury (TBI), or concussion, happens when a bump, blow, jolt, or other head injury causes damage to the brain. Every year, millions of people in the U.S. suffer brain injuries. More than half are bad enough that people must go to the hospital, and the worst injuries can lead to permanent brain damage or death.

    You do not need to seek immediate medical care. Make sure your symptoms do not change. If they do, go immediately to the ER. If not, follow-up with the doctor in the coming days.

    You should go to the hospital immediately. More than half of Traumatic Brain Injuries are bad enough that people must go to the hospital.

  6. 6.New Migraine

    Migraines are headaches of moderate to severe intensity, which happen when blood vessels in the brain swell up. They are episodic and thus can recur often. Most migraine sufferers experience increased sensitivity to sounds and/or lights and become nauseous and vomit.

    You can safely treat this condition on your own. Migraines are diagnosed purely by your symptoms. Medications, such as over-the-counter pain killers (e.g., ibuprofen or Tylenol) may help. However, it is important not to take them too regularly. Taking them more than two or three times a week can cause more headaches, as the body gets used to the drug, and the headache comes back when you stop taking the medication. Talk to a doctor if you have two or more migraines each month, as there are more effective treatments for preventing migraines.

    Rarity:
    Common
    Top Symptoms:
    new headache, fatigue, nausea, mild headache, sensitivity to light
    Symptoms that always occur with new migraine:
    new headache
    Symptoms that never occur with new migraine:

    If the rash itches, an antihistamine such as Benadryl can help relieve symptoms. Otherwise, Pityriasis rosea does not require any treatment.

    Rarity:
