Husband, age 64, has high blood pressure and is taking 2 medications: Amlodipine besylate 10mg; Lisinopril-Hctz 20/25mg. This morning his throat started swelling and his voice is affected, now his lip is swelling. We thought it could be some sort of allergic reaction from unknown cause. He took a benedryl and says throat is getting better. Did not eat or drink anything unusual today. He had an insect bite on back of neck yesterday. This is Minnesota fishing opener today and he touched frozen minnows and went fishing most of the day!
