Suggest Treatment For Severe Chest Congestion Along With Wheezing

I went to my doctor yesterday with symptoms of a respiratory infection. I began coughing up bright red bloody mucous, and my stools have been very dark black for two days now. He prescribed an antibiotic and also an acid reducer, thinking that acid reflux is aggravating my problem. At night I can hear gurgling sounds in my chest, like air bubbling through fluid. Today I feel weak, and get dizzy very easily. I am supposed to return in three weeks, but does this seem like something that may require a more immediate return? I fear I may have a hole in my esophagus.
