HELLO, I take a Lisinopril (20 mg) with 12.5 HCTZ for blood pressure. I have the following issues and i want to know if HCTZ the possible cause: Soaking night sweats (not TB, I checked) Cracked skin at the bottom of my feet. Occasional leg cramping joint pain in ankles, knees and hips that comes and goes numbness in the ends of my feet.A couple trips to the bathroom every night More often general tired - probably from lack of sleep from bathroom trips. I m a male, 70 years old. More than average in activity for age. Working 1/2 time in industry. Was feeling fin until I started on BP meds. Thanks, John Whalen
