Why do your eyes swell after crying?

There are many people who develop swollen eyes after crying. Since the skin of the eyelid area is very thin and the subcutaneous tissue is loose connective tissue, it can easily cause edema. Especially after crying it can lead to an accumulation of tissue osmosis under the skin of the eyelid, and many friends will constantly rub their eyes with their hands when they cry, which can aggravate the edema, and some people even rub their eyes with their hands leading to a situation of infection and the symptoms of conjunctivitis. So the swelling of the eyes must be carefully observed, whether it is simple edema or caused by infection, simple edema can be eliminated by cold compresses, if the infection is caused by the need to use local drugs to symptomatic treatment.
