Greetings, thank you for your question.

I understand your concerns, I will try to help you.

There are several reasons why you may have a headache and nausea:

• Migraine problems
• High blood pressure
• Early stage stroke problems
• Dehydration
• Lack of exercise or outdoor activities
• Stress and emotional disorders
• Unhealthy eating habits such as slow eating
• Lack of rest or sleep.
• Thyroid problems.
• General diseases such as red blood cell deficiency
• A bacterial infection of the sinuses that can cause sinus headaches. (sinus inflammation)
• Bacterial infections of the brain or meninges

Or it might be Post-COVID or Long-COVID. According to world and Malaysian health bodies such as the CDC and MOH, former COVID-19 patients can experience long-term symptoms after recovering from the infection as early as 4 weeks or longer.

I highly recommend you speak to your doctor regarding your situation to provide you with the safest and best route of care to manage your condition as a whole. You can contact our doctor online for further information and treatment.

I hope this answer helps you. Thank you.
