Im 68 years old and within the past three weeks I have noticed my face swells on only the right hand side during sleep. this morning I look like I might have had a stroke because it remains swollen and iv been up for hours. I do get sinus infections but never had this reaction.
General swelling in the area can also be caused by trauma or injury to the face (perhaps caused by dental procedures etc.). Infections can also cause swelling to the face, such as orbital cellulitis or angioedema. Orbital cellulitis can be dangerous and so should be checked by a medical professional. At the same time it is important to rule out kidney disease which can cause swelling in the face as well as other areas of the body. A lack of sodium (salt) in the diet may also lead to water retention. Another possible cause is that if the cause is allergy, that the allergy is to a detergent etc. that you use on your bedsheets and pillow case.
