I have been taking Lisinopril for years without much in the way of side effects. Now I am having issues with numbness, prickling, tingling, etc. These began in early May. I have a head CT and MRI, a carotid Doppler, a Lyme disease test, a vitamin B test, and my sinuses thoroughly checked out. All of these tests have showed up no issues. I have just thoroughly read the list of Lisinopril side effects. I am going to talk with my internist about changes BP meds. My BP has vascillated more lately as well. I was wondering if I should hope to stay with ACE inhibitors since I tolerated one and it worked so well for many years.
