Ive been on Lisinopril for 2 months. Ive had a cough for the last 3 weeks. Started with the worse cold ive had in years. I cant sleep at night cause i cough so hard. My sides and back hurt all the time. I thought maybe i had a sinus infection, but the cough and runny nose is clear. I also have a headache all the time. I went on this med cause my insurance company wouldnt pay for my Macardis, which worked great. I think we are all victims of the insurance companys. I will be going to my Dr soon and getting off this junk.
