Thanks for writing to us.
The persistent pain in the chest wall is likely to be due to the persistent cough
you are having. It can be allergic or infective in origin. The continuous cough can precipitate a preterm labor
. You need to have a steam inhalation and lozenges to suppress the cough. Rest and hot fomentation to the chest will help.
I hope this information has been both informative and helpful for you.
