I am on Meloxicam and Lisinopril. Last night (3:00am) I was not able to swallow, it seems some thing was swollen in my throat. I had to sit up in bed, waited several hours to be able to swallow and it hurt bad. Several hours later one side of my throat give a little relief. I took my Lisinopril, and drank a little water. About 10:00 am I took a allergy relief medicine (over the counter) brand. I am thinking I had a allergy reaction to something. About 2:30pm I was able to drink a cup of coffee. My throat was clear on both sides. No pain. Could you explained to me what happen? Was that allergy reaction??
