Hi I am 20 years old, female, and I have been coughing up blood at least once a month for about a year. I have seen many doctors however, they said I have asthma and gave me an inhalor, but my symptoms are not being treated. They diagnosed me with asthma almost two years ago. I have had x-rays, ekg's, blood/urine tests. They said they didn't find anything and sent me home. I'm still coughing deeply. Now I'm getting dizzy spells almost everyday. I eat and drink right. My chest hurts. And little amounts of blood appear. I am a musician and I can not sing without coughing up blood afterwards. What do you suppose it is? Do you think it is serious?
