You need to get to a doctor ASAP. Coughing up blood is nothing to take lightly.
I've already been to the doctor, he gave me antibiotics.
From talking to some friends and close relatives, I hear that coughing up blood is actually quite common when you have a bronchial infection. My aunt, who has never smoked anything in her life, said the same thing happened to her when she came down with bronchitis. She had blood in her mucus she coughed up for about 3 days.
Also, my cough is extremely dry, which leads me to believe the blood is at a minimal level.
I've been to the doctor 4 times in the last 2 weeks, and quite frankly I'm sick of going. Every time I go, I already know what is wrong with me, and simply have to go so my insurance can be charged, and I can get the prescription I already knew I needed, usually 2 days late because Oral Surgeon's apparently have a hard time squeezing in appointments for post-operative complications...I'm sure their profit margin is much smaller for such instances.
