<s>[INST] I ve had off and on blurry vision. On and off hign pulse. But today I have a headache. Stomach is tight and burning. Blurry vision. And overall feel icky. I have lupus so I discount a lot of odd symptoms. But today I m really alarmed. What could it be? Do I call regular dr. Cardiologist or optimologist? [/INST] Hello! Welcome and thank you for asking on Chat Doctor! Regarding your concern, I would explain that your symptoms could be related to inflammation. I recommend you to closely monitor your blood pressure and heart rate. It is important performing some tests to determine the cause of your symptoms: - lab blood tests (complete blood count, thyroid hormone levels, PCR, sedimentation rate, blood glucose)- a resting ECG and cardiac ultrasound to examine your cardiac structure and function- a brain MRI. The blurring vision and headache could be related to possible intracranial complications of lupus. That is why a brain MRI is necessary. Hope you will find this answer helpful! Kind regards,  </s>
