Hi, My husband is 41 years old, and he has been on Lisinopril 20 mg for about 6 months. He is experiencing dizziness, numbness on his feet due to that he is unable to walk at times. He also has chest pain in the morning, which wakes him up and lack of sleep at times and memory loss. Since he has been taking this medication he is experiences extreme tiredness. The worst of all is the palpitations. The doctors are unable to find anything wrong with him. He had Cardiac Catheterization, and stress test and all come back normal. We do not know what do at this time. Regards,
