I have been taking 20mg of Lisinopril for about 6 months. At first my blood pressure came down to an acceptable level, but now seems to be creeping up again. I know this means a higher dosage, but I am reluctant to take it as I have developed ....not a cough as such, but when I go to bed especially, it feels like I have a lump of mucus in my throat and have to keep swollowing, but it doesn't go away. This is accompanied by a burning in my throat which I get any time of the day. Last night I had terrible chest pains together with all the other stuff I didn't sleep a wink! when I reported these symptoms to my doctor she said I has asthma and gave me an inhaler to use, but this has not got rid of my symptoms. I am sure it is the lisinopril.
