Knees and toes symptoms and conditions

I'm 57, female and have been taking Lisinopril since July. The cough appeared quickly, then the fatigue. Now I am experiencing the joint pain mainly in my fingers, shoulders, knees and toes. Occasionally I get shortness of breath and the fluttery heart palpitations . My blood pressure is way down though and I've been feeling more light headedness lately. I'm going for a follow up with the doctor and will discuss these symptoms with him and see what he says. My dosage is 12.5mg.

I was taking 500mg three times a day. After 1 week I developed severe joint pain and swelling in my fingers. I got an itchy rash on the bridge of my nose and over my eyes and inside my nose. The joint pain continued to my knees and toes. I have been off of the medication 3 weeks and I am just starting to feel a little normal. a different doctor put me on 800 mg of Ibupropen 3 times a day and after reading up on the side effects of Cephalexin I began taking Benadryl which has helped a lot.
