Benicar and pap

I started with Lisinopril and had severe isolated visceral angioedema. Thought I was going to die. The attacks felt worse than childbirth. Urine flow would totally stop and bladder would cramp. Bowels would not function. Over a 10 on the pain scale. Went off Lisinopril and 3 days later Dr. wanted me to start Benicar. Within 5 days I was in emergency room with visceral angioedema even worse than the Lisinopril. I have had CT scan, ultrasound, numerous blood and urine tests, PAP, colonoscopy and everything is negative. It has taken a full week for all symptoms to stop. I finally feel normal again after 2 months. I cannot take this family of drugs. And Dr.'s need to be more informed about this serious side effect. My Dr. never considered it could be the Lisinopril or the Benicar since I didn't exhibit any facial edema. More information about this rare, but serious side effect needs to be published.
