hello, my throat has been having issues over the past weeks. I coughed up blood a couple of times after smoking. I panicked and went to the doctor which x-rayed my throat and chest, and did a blood test. Everything was normal; he gave me naprox, which ive been taking for a week. However, my throat still feels very weird . I smoke a cigarette and it swells up and tightens, feels like this most of the day, but worsens after smoking.
