I am 33 yrs old. One night I was sleeping and about 12am, I woke up with my heart racing and I was having a squeezing feeling in my chest. I went to the ER and my blood pressure was extremely high. However, when they were running tests on me, they found that I hadn't had a heart attack and I was diabetic. The doctor gave me a stack of prescriptions to start taking. A few months later I went to see a different doctor, one that accepts my discount plan, and he took me off everything but metformin and 5 mg/day lisinopril. Since that night, the beginning of March, I am not the same person. I am keeping my diabetes under control, and my blood glucose is always in normal range. My last A1C test was 5.8. However, I am to the point of paranoia concerning the dead tingling feeling that I have in my feet. It is very on and off. There one minute then gone the next. It's not a feeling of numbness, because I can feel the slightest touch. Now from very little research I have already come to a conclusion that its the lisinopril. THE COUGH is enough to make me depressed and moody on its own, but now I'm thinking that my major mood swings are also coming from this drug. I cry all the time because I am worried that the diabetes is effecting my feet and that is what the doctors tell most people. My doctor said that I haven't been diabetic long enough to worry about neuropathy and that the sensation in my feet could be from a million things. Then almost every website I've looked at so far has hardly anything good to say about Lisinopril. I want to stop taking it, but don't have the money to afford an expensive medicine. what should I do? My blood pressure is usually around 102/68-70
