This is Dr Basu, experienced Internal Medicine Specialist.
I am here to address your concerns and provide great service.
Your symptoms do suggest muscle sprain related issue.
You may have ruptured few muscle fibers from coughing.
May take several weeks to heal since you are still recovering from bronchitis.
A stronger cough suppressant is recommended to help with the healing process.
Avoidance of any stretching activities to rest the ribcage muscles is recommended highly.
A combination oral steroid and opiate medication may be helpful to control the pain.
Please see a local doctor for further evaluation.
It was my pleasure to help you today.
