Patient : I've been coughing since Friday and my chest hurts and it's
difficult to breathe a little. I went to the doctor yesterday
and he checked my chest and said it was just a cold.
I do have post nasal drip and my head is hurting. He told me
to start Mucinex DM. I did yesterday all day and it helped with
the coughing but I took it today and I am still coughing and my
chest is hurting. He gave me Z pack to hold onto if I am not
better by Wednesday. How long does Mucinex take to work? Should
it already be working by now? And if I take the Z pack will it
