### input:
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 witChatDoctorplete 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!

Thanks for your question on Chat Doctor. I can understand your concern. Sudden onset breathlessness, dizziness, numbness, shaking, collapsing, loss of vision and ringing in ears are seen with 1. Pulmonary embolism 2. Heart diseases like heart attack 3. Epilepsy (seizures). So better to consult doctor and get done 1. Clinical examination of whole body. 2. CT or MRI of brain and EEG (electroencephalogram) 3. CT pulmonary angiography for the diagnosis of pulmonary embolism. 4. ECG and 2d echo for heart diseases. If all these are normal then sometimes stress and anxiety can also cause similar symptoms. So consult doctor and discuss all these and first rule out major diseases. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
