High blood pressure, type 2 diabetes. Take Synthoid, Spironolactone,Glyburide,Lisinopril (25/20) Atenelol,Metformin., Amlopodine (Norvasc). Spironolactone is only new one recently added. Since taking these meds, am having intense night cramps on legs and feet. Is this a side affect of one of these meds? Will increasing water intake adviseable to get rid of cramps?
