So A Few Weeks Ago I Tried Cocaine For The

So a few weeks ago I tried cocaine for the first time. In the days after I developed a cough that produced a yellow mucus with spots of bright red blood. There was never much blood but enough to have me worried. It's about 3 weeks later now and I still have an awful cough, nasal congestion, and headache. I went to the doctor today to get my blood checked for a platelet deficiency and my white blood count was 21.4. over double the limit of 10.3. Did i have an allergic reaction to the drugs or is something else going on? The doctor I went to said I had a bacterial infection but did not know about the cocaine or blood.
thank you
