Hi
Welcome to the MedHelp forum!
If along with swelling you have discomfort opening your mouth or while chewing, then the swelling could be due to TMJ. Other possibilities are dental infection, cellulitis (infection under the skin), lymphedema (due to faulty lymph channel), sinusitis affecting the maxillary or cheek bone, or a deep seated cyst.
If you have swelling only in one half of the face, then the cause has to be local. It can be ear infection, dental infection, local cancer or even blockage of salivary glands. It can also be chronic sinusitis. The other possibility is a venous or vascular pooling due to clots or deep vein thrombosis.
Do discuss this with your doctor and get yourself examined. Take care!
Hi, You could have an ear or tooth infection either way i would see a doctor fairly soon. Good luck
