I am 32 year of age.Recently I got wet by rain following that swelling came from below my ears.I showed it to one doctor and he gave me some pain killer which caused acidity and my stomach got swelling so I had to stop the medicine.On top of this I have dimness of vision what could it be due to. There is large vein that is coming from top of my eyes it ends in back spot on top of my eye it self is this any sign of any thing.
