An allergic reaction, a sebaceous cyst, an injury, acne, a skin infection, a tooth abscess, a boil, an ingrown hair or cellulitis can cause a lump in the cheek, according to Healthgrades. Additional causes include lymphadenopathy, mumps, keloids and cancer. If unsure about the origins of a cheek lump, consult with a qualified medical professional for diagnosis and treatment if necessary.
If a rash, tongue swelling, breathing difficulties, choking, facial swelling or wheezing accompany a lump in the cheek, a person may be suffering an extreme allergic reaction known as anaphylactic shock. If this is the case, emergency medical attention should be sought immediately, notes Healthgrades. Mumps also constitute a medical emergency and often produce symptoms, such as a fever above 101 degrees Fahrenheit, along with jaw swelling.
Additional symptoms can manifest depending on the cause of a person's cheek lump, to include rashes, bleeding, itchy eyes, sneezing, bruising, redness, hives and oily skin. It is important to visit a doctor, so that they can assess the full range of symptoms and administer any necessary medical testing to form a proper diagnosis. Doctors are likely to question the patient about their medical history and ask detailed questions about when the lump first appeared, if any injuries to the face have recently occurred and whether or not any pain is present. Additionally, they will ask if the patient has used anything to treat the lump, if the patient is on any other medications, and if the patient suffers from allergies, notes Healthgrades.
