Heavyness in upper eye muscle. Feels as though its mushy. I can actually grab a small fatty growth from between eye socket with my fingers.?

Difficult to say. Could be some orbital fat prolapse. Could be an enlarged lacrimal gland. Could be some plugged skin gland. Or it could be some sort of tumor. Have it examined.
Edema. It is very possible to collect fluid, or edema in this area. Please see your doc to check for abnormal fluid retention issues, thyroid problems. Thx.
