Hi can i know the cause , prevention and tratment of under eye skin swelling at morning ??

AM eye swelling: Do you have allergies, a runny nose or post nasal drip, reflux? All of the above irritate the nose and cause discharge ,at night when you sleep,since the head is down the fluid runs into the eyes and causes swelling. Elevate head of bed when sleeping , take an antihistamine before bedtime, treat reflux, avoid allergens. F/u with doctor/urgent care
