Can I have damaged 1 of my back muscles because I have bronchitis?

Recently I was diagnosed with Bronchitis .The infection Is only in my right lung and earlier today I sneezed after that i had to cough, when I cough I felt a pop in my back right away I felt pain really bad I barely could stand I couldnt sit down, I can't bend over I was wondering if this is due to the bronchitis infection or did I really hurt my back ? The pain is in my right Mid to lower back please help.
