Are these symptoms of lung cancer?

[swckv]

For the last month I am sneezing up blood and coughing up blood(coughing up blood not sure if it is from nose), have headache all the way down the middle of the brain and when I swallow, also I am short of breath and wheezing, also have chest pain and back pain, right now I have itchy back. But, I had an x-ray 6 months ago that showed clear lung. I had 6 x-ray in the last year due to recurring chest pain.  What is wrong with me.? Is it allergy or asthma?
