64 years old, diabetic, recent cancer surgeries (otolaryngologist), just finished 33 radiation treatments: second time today, had a weird feeling of not being able to focus my eyes together (have worn glasses since childhood) but feeling is like right eye is operating independently from left eye. No pain, and lasted only short time. Sign of stroke? already have doctor appt tomorrow afternoon for consult on current medications includi ng liquid hydromorphone for post surgery and radio pains... just leave this situation until then and explain it to him? Am feeling ok now, no dizziness, no vision problem, no pain.
