Hello , Last Tuesday I started with a sore burning throat that lasted only 2 -3 days at the most. I then started spitting up large amounts of mucus and blowing huge quantities out my nose for another 3- 4 days without fever. My problem is that I cough so hard like projectile that I damaged muscles or disc in my back and everytime I cough it feels like sharp knife pains in lower back. I took theraflu fir first 3 days...then robitussin for 2 days and I couldn't stop coughing and spitting and blowing so my wife picked up delsym the grape stuff for cough only...first time I took it my face turned really red....second dose my eyelids swelled up. So today I called my primary care VA dr. As I'm a vet and my dr. And nurse both went on vacation until after the first week of the year. I'm doing heat and ice and massage on the back but after several coughs I have to use a cane to bend or walk I'm 48 yo male in pretty good shape...I just noticed b4 writing this I have mucosa pockets in the back of my throat. Please help...back really hurts to cough and afraid to take anything as of now. Ty kindly in advance. C
