Is crying an inflammatory process?

After I cry, especially for a while, my eyes feel sore and my eyelids get puffy and red, and they can take almost a day to feel back to normal. I also feel tired for the next +/-12 hours. 

Is there an inflammatory feedback mechanism from crying? 

Also, this brings up another question: does anyone know the scientific or evolutionary origin and purpose of crying? Is it an adaptation? 

Thanks 🥲

It's a release of certain hormones, whether it's a sad or happy cry, that can cause swelling/inflammation of certain glands and ducts around the sinuses. This is a automatic reaction to keep producing moisture so neither your eyes or sinus drys out to a detrimental point.
