I am a teacher and i may have high blood pressure but Im not taking medication for it. Been like this for 2 days. [/INST] Hello and thank you for using Chat Doctor. I carefully read your question and I understand your concern. High blood pressure might be the cause of your symptoms. Sometimes a lot of people does not feel anything even having high blood pressure. But sometimes, excessive blood pressure in a hypertensive rise can be manifested with headaches, blurred vision, nausea or vomiting, increasing confusion or lightheaded, chest pain sect. So, first I will recommend you to measure your blood pressure. If you have elevated values, meaning mean values above 140/80 mmHg than you have to treat it. If I was your treating doctor I will recommend a full check up with blood test analyze, an electrocardiogram, echocardiography and a pressure holder monitoring. Only after this we can be able to judge to start a medication or not. If we don't find hypertension we can than look for other causes of your symptoms like cervical problems or neurological. Hope I was helpful. Wish you good health. Best regards. </s>
