Top 10 Sores on the Inner Cheek Causes

  1. 1.Cold Sore

    Cold sores (also called oral herpes or fever blisters), are viral infections of the mouth caused by the herpes virus type 1. You were probably infected very early in life as a child when an adult kissed you. The virus stays asleep (dormant) and causes infections every now and then after exposure to lots of sun or emotional/physical stress. It is contagious when an outbreak is happening, but treatment is limited unless you are immunocompromised.

    You can safely stay home or try some minor treatments. As a viral infection, it will go away on its own without antibiotics. Balm mint cream (1%) or topical rhubarb-sage cream may improve symptoms, but it's not standard treatment.

    Rarity:
    Uncommon
    Top Symptoms:
    mouth lesions, pain on the outside of the lips, itchy mouth, burning pain on the outside of the lips, lip numbness
    Symptoms that always occur with cold sore:
    mouth lesions
    Urgency:
    Self-treatment
  2. 2.Canker Sore

    Canker sores are small, grayish-white sores in the mouth, often on the inside of the cheeks, lips, and on the tongue. No one really knows why canker sores happen, but it seems to be inherited and susceptible to vitamin deficiencies and allergies.

    You can safely treat this condition on your own using Chlorhexidine mouth washes (Peridex or Periogard) or steroid medications (Orabase, Betnesol, or Ovar).

    Rarity:
    Common
    Top Symptoms:
    painful mouth sore, numerous mouth sores, mouth sore surrounded by a red area, single mouth sore, oral ulcer
    Symptoms that always occur with canker sore:
    painful mouth sore
    Urgency:
    Self-treatment
  3. 3.Mucous Cyst (Mucocele)

    A mucocele (mucous cyst) is NOT a serious tumor. It's typically caused by repeated biting leading to leakage of mucous from damaged mucous ducts, which accumulates and creates a cyst. It's most commonly found in kids, and usually inside the lower lip but also possibly under the tongue or in the inner cheek.

    You should go to your primary care doctor OR an oral surgeon in the next week or so. There, the doctor can cut out the mucocele and treat it for good.

    Rarity:
    Common
    Top Symptoms:
    painful mouth sore, painless mouth sore, single mouth sore, sores on the inner cheek, sores on the inner lip
    Urgency:
    Primary care doctor
  4. 4.Oral Herpes

    Herpetic stomatitis is a viral infection of the mouth that causes fever and red and inflamed gums. This typically happens early in childhood.

    You can safely treat this condition on your own because it goes away on it's own. Anti-viral treatment is reserved for those who are immunocompromised or with severe cases. Acetaminophen (Tylenol) or ibuprofen (Advil, etc) works to help with the pain. No antibiotics are useful.

    Rarity:
    Rare
    Top Symptoms:
    gum pain, painful mouth sore, fever, gum swelling, mouth sore surrounded by a red area
    Symptoms that always occur with oral herpes:

  5. 5.Obstructive Sleep Apnea

    Sleep apnea is a disorder in which the upper airway is obstructed during sleep, which causes poor sleep quality and frequent awakening.

    You should visit your primary care physician within a few weeks to discuss your symptoms. The physician will likely order a sleep test to confirm the diagnosis.

    Rarity:
    Common
    Top Symptoms:
    fatigue, irritability, daytime sleepiness, trouble sleeping, sore throat
    Urgency:

  6. 6.Influenza

    Influenza, or Flu, is an infection of the airway caused by the flu virus, which passes through the air and enters the body through the nose or mouth. The symptoms are similar to those of a cold, but the flu is usually more serious.

    If your flu-like symptoms are existing for less than 48 hours, it might be helpful to seek care by telephone or in a walk-in-clinic to get a course of oseltamivir (Tamiflu). Most people will get better on their own by drinking lots of fluids and taking an over-the-counter medication such as acetominophen (Tylenol) to help with aches or fever.

    Rarity:
    Common
    Top Symptoms:
    fatigue, headache, loss of appetite, cough, muscle aches
    Symptoms that never occur with influenza:
    headache resulting from a head injury
    Urgency:
    Phone call or in-person visit
  7. 7.Non - Specific Skin Rash

    A rash is an area of irritated or swollen skin. Often, rashes are unidentifiable and some variation of normal. For example, scratching one's arm causes it to turn red (which is caused by mast cells releasing chemicals into the local area), but that's completely normal.

    At this time, you do not need treatment for this rash. If it worsens, you may need to consult a physician.

    Rarity:
    Common
    Top Symptoms:
    rash
    Symptoms that always occur with non-specific skin rash:
    rash

    fatigue, difficulty concentrating, loss of appetite, decreased sex drive, unintentional weight loss
    Urgency:

  9. 9.Common Cold

    The common cold is a viral infection of the upper respiratory tract.

    The common cold is treated symptomatically. Since this is a viral infection, antibiotics are not effective. You can safely treat the symptoms of this condition with over-the-counter pain relievers, decongestants, antihistamines & cough medicines.

    Top Symptoms:
    fatigue, headache, cough, sore throat, congestion

    Dry skin can be caused by overheating during the winter or air conditioning in the summer, the loss of sweat and oil glands as you get older, and overuse of things like soap, antiperspirant, perfumes, and hot baths.

    You can treat this at home by using a moisturizer to reduce water loss and soothe the skin.
