Summary

This trial investigates whether a single steroid injection into the arm muscle can reduce symptoms of unexplained chronic cough. About 40 adults with chronic cough that has no clear cause will receive either the steroid or a placebo injection. Researchers will track changes in cough severity and quality of life over several weeks to see if this easy-to-administer treatment offers real relief.
