Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. Elevated blood pressure may cause headache and pressure feeling. Other possibilities like enteric fever or sinusitis or tension headache etc. Until examination is done it is difficult to say what it is. Use anti hypertensive drugs as per your doctor advice. Take low salt diet, avoid smoking and caffeine drinks. avoid alcohol. If symptoms not improved please consult your doctor he will examine and treat you accordingly. Hope I have answered your query. Let me know if I can assist you further.
