My husband was recently diagnosed with pulmonary carcinoid in 2/06. In order to make the diagnosis, he had to undergo a Thoracotomy. He developed post operative pnemonia. I would recomend that you get a cbc, chest x-ray and a repeat chest cat scan. I dont know what type of antibiotics you had, but you need a flourilquinoline, oxifloxin, levaquin or cipro for at least two weeks. If that doesnt help consult a pulmonologist of infectious disease doctor, if your oncologist is not being helpful, try MD ANDERSON cancer center in Houston Texas. Good Luck and God Bless.
Also try Notuss cough syrup, it seems to keep my husbands cough under control, its a narcotic cough suppressant with out a lot of side effects.
