<s>[INST] I was told to take benzonatate 100mg 3days ago. It hurts under my shoulder blade really bad. My cough is now unproductive. I just read that this shouldn t have been prescribed if my cough was productive, which it was. I think the prednisone is fine but now I m not coughing up that phlegm and I hurt.
