Mussel symptoms and conditions

I took Lisinopril 10 mg for about 10 days. My doc had told me that 5% of those tested developed an itchy cough, and to stop if this happened to me. I stopped as soon as the cough developed. That was more than a week ago. I haven't been able to get a night's sleep since then. The cough is dry and hacking and continuous. Coughing can also come at any time during the day. Sometimes a coughing attack hits when I already have a cough drop in my mouth.

I feel just the same as I've felt when experiencing a sinus infection, with nighttime drainage and sinus headache.
When I called the doctor's office, I was advised to take an over-the-counter cough med. It hasn't helped. I am exhausted.

This seems to be a case of the "cure" being worse than the initial problem.
