What Can Cause Discomfort In Left Lymph Node With Debilitating Pain And A Nausea Feeling?

discomfort in left lymph node below ear, dibilitating pain in right eye and discomfort in right temple. This is accompanied with nausia. Went to eye dr fearing glycoma. Eye pressure ok, but after assistant place eye drops and later dilated my eys, the MD kept looking intensely deep into my eye with a bright light presumatively through my eye lens. After eyes were dilated and in the waiting room, the pain almost completely dissipated, as did the discomfort in the temple and lymph node. Any ide of my problem?
