Top 10 One - Sided Scalp Swelling Causes

  1. 1.Kidney Infection (Pyelonephritis)

    Pyelonephritis is the medical term for a kidney infection. This can arise as a result of a bladder infection that travels upstream. A kidney infection is usually bacterial in nature, and can cause pain on the side of the stomach, high fever, nausea, and blood in the urine.

    You should visit your ER. Pyelonephritis is caused by bacteria and, therefore, needs to be treated with prescription antibiotics.

  5. 5.Urinary Tract Infection

    In women, the opening to the urethra (the tube that carries urine from the bladder to the outside of the body) is very close to the anus, and bacteria from the anus can easily escape and travel up the urethra. These bacteria can infect the bladder, and cause what is known as a urinary tract infection (UTI).

    You should go to your doctor, an urgent care, or a walk-in clinic to be treated. UTIs must be treated with antibiotics. It is important to get treated as soon as possible to avoid the infection from becoming worse and spreading. To prevent future UTIs, urinate frequently, wipe from front to back, and urinate after sex to rinse out bacteria.

  10. 10.Tension Headache (First Onset)

    Tension-type headaches are the most common type of headache. It is pain or discomfort in the head and/or neck. It's often associated with muscle tightness in these areas. This condition can occur as little as once a year (infrequent) 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, 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. If these headaches become more chronic in nature, you should visit your primary care physician, as chronic tension-type headaches can be more effectively treated with prescription medications and additional non-drug therapies.

    Rarity:
    Common
    Top Symptoms:
    new headache, nausea or vomiting, loss of appetite, moderate headache, mild headache

    Self-treatment
