I am having coughing and a little sinus drainage . This is the third time since June 4. I was put on an antibiotic the first two times. I got better but after the RX ran out I had the same symptoms . THis time I was given methylprednisolone. My regular doctor can not see me for almost a week. A walk in clinic is the ones who took care of me all three visits. Does this seem like the correct thing to do?
