<s>[INST] Hi, for the past 3 days my feet and legs...it feels as though I am standing on a motor, they feel as though they are vibrating. I am 69 years old and female. I do sit a lot and try to walk often as I have bad knees, but it is becoming aggravating to me and I am getting worried . I am on Atenolol, Furosemide, Potassium and Losartan. Thank you, Laverne Washington [/INST] You are a High BP patient on three antihypertensives. I would like to know about the present BP control and if the same has been long-standing and what effect it has had on your heart, kidneys and on your central nervous system. As far as the knees are concerned, I don't think that is an issue here. What is not understood is WHY YOU ARE ON POTASSIUM SUPPLEMENTS! Diet can be adjusted to have sufficient intake of potassium that our body needs. Increases in potassium level can lead to muscle weakness and catastrophic heart issues...beware. Kindly get your blood electrolyte levels checked soon. </s>
