What can cause one-sided headaches and a blackout?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hi doctor,

My head hurts a lot on the right side, especially around the temple area. Sometimes, I have headaches spreading to my right eye. It is tolerable, but when I lie down, it becomes more painful. My stomach hurts a lot. I feel nauseous too. In the morning, I experienced a weird thing. During breakfast, I felt nauseous.

Suddenly, my eyesight became blocked with black and white dots. My ears were ringing. I closed my eyes, thinking of it as an illusion. When I opened my eyes again, black and white dots were still there. I felt weird all over my body. I have a tingling feeling in my limbs, and finally, the black and white dots in my eyes cleared after looking down.

After that, I had wetness between my legs, and so I urinated. I felt like I was blacking out. I have a blood pressure of 90/70 mmHg and a temperature of 36.2 degrees. I have a pulse rate of 82 beats per minute with a blood saturation level of 97%.

Kindly help.

Hi,

Welcome to icliniq.com.

Your headache seems to be of the migraine type. I suggest you take a tablet. Celecoxib 200 mg twice a day for pain and Topiramate 25 mg at bedtime for a week. Have a follow-up after a week of taking Topiramate. I suggest you check your CBC (complete blood count) for anemia and your serum electrolytes to rule out blackout. These results will help to understand your condition better.

I hope this helps.

Thank you.
