inflammatory conditions
"I started the Dexamethasone 4MG only two mornings ago. The second day (yesterday) most of the pain was gone. However, beginning yesterday I've had 9 or 10 bouts of hi-coughing. Including 2 to 3:30 this morning. That symptom is not listed anywhere but it does seem odd that I hadn't suffered hi-coughs in years and years and never this long lasting. 
Until speaking with my physician in the morning, I'm having to suspect an interaction with other medicines."
