I have been on Lisinopril 2.5mg for HBP for a few months now. Not thinking it had anything to do with anything, I started to develop severe muscle and joint pain in my hips all the way down to my feet. I was starting to think I had arthritis or RLS. The pain is really bad and I have taken ibuprofen and used muscle rubs without success. I went on vacation for a week and accidentally forgot to pack the med. Well I had no problems until when I came back and started back on it. The pain has gotten so severe that I called my MD. She recommended I stop taking it and see her in a week. I even ordered a tens unit and started taking potassium supplements. I see on some posts not to take the potassium so I will set that aside for now. As for the coughing, I am a smoker and cough and hack my brains out anyway. So I can't really say its making me cough. This pain though has kept me up at night and I toss and turn because of the pain. I hope now that I stopped taking the med these pains will subside soon.
