Hello, I thought I had a head cold and went to the doctor last week, I had a bad chesty cough, headaches, he checked my chest and listened to my breathing, he diagnosed I had bronchitis, he put me on an anti biotic and said if I get worse or no better to come back. This morning I woke up and starting coughin badly, I coughed up some blood along With green phelm, I have tightness to my chest when I take deep breaths and my ribs are a little sore, the doctor has put me on a stronger anti biotic now, just worried it may be something worse?
