Last night I had an odd episode and trying to figure if it warrants seeing a doctor. I am a 31 year old female about 140 pounds and had a healthy physical last year. But while swimming at my friends house late last night I encountered heavy breathing, loud ringing in my ears, loss of vision, shaking, dizziness, numbness in my hands, and almost completely passed out. My friend noticed my pale face and white lips and had me lie down. After an hour I felt good enough to drive home where I vomited the rest of the night with complete exhaustion. Today I still feel weak and moving fast still takes my vision and I did have ringing in my ears for about a minute with spots floating in vision while sitting. Can someone please give me some advice? Thanks!
