<s>[INST] I have really high blood pressure lately, dizziness and fatigue. Most recently I have a sensation in my leg that is painful to the skin touch.. also , once in a while I will get a pulsating pain that lasts for just a minute. Yesterday as I was sitting at my desk, I had a heat sensation in my back and then i broke out in a sweat. What might be going on? [/INST] Hello, High blood pressure per se may cause the symptoms of headache, dizziness and fatigue. Treatment of hypertension with lifestyle change or medication such that the blood pressure reading is below 140 mg / 90 mg should be the priority here. Also, if you are more than 45 years old, obese, smoke or have other risk factors, a cardiac evaluation by doing a and ECG and If needed and 2d Echo and TMT should be considered.  However again the sweating episode can still be due to fluctuation in BP. Hopefully I could help Regards  </s>
