What Causes Pain In The Right Side Of The Body Upon Coughing?

I had allergies, which turned into a sinus infection, treated for that, then it turned into bronchitis, which I ve suffered with a lot of my life. We have had to move during all of this and my coughing is always and has been severe. A few days ago, and have been lifting, my lower right side started hurting, especially when I cough. I realized I may have pulled muscles from coughing and moving. But, just a few minutes ago, I went to cough, a severe pain came in the same area, but I felt a pop. So severe my husband is holding my side so I can cough. Is this still muscle related. (I ve already finished two different rounds of antibiotic and 2 kinds of shots and steroids).. to much. Thank you
