Coughing up blood

I'm a 38 year old male, non-smoker  who has been in good shape all of my life.  My family and I recently moved to Indonesia, and since coming here I've dealt with the typical sicknesses as your body adjusts to the new environment.  I also came down with a pretty severe chest cold about a month and a half ago.  Through it all I've lost about 16 lbs since arriving.  2 weeks ago, after working out, I began couging severly for about 30 seconds.  After it ended I began couging up a small about of blood.  In all it probably measured up to almost a tablespoon, and then ended.  The next morning my chest felt like someone had hit me with a baseball bat.  I went to the doctor the following day and he listened to my lungs, did the normal pushing of my stomach, checked ear, nose, and throat, and ran some blood tests.  He did not do a chesy x-ray, and didn't seem interested in doing one.  He said the lungs sounded clear so why waste your money?  Everything came back clear, and the doctor said that I was probably dealing with the tail end of a viral infection.  Then last night, after swimming laps in the pool. I started couging again, and up came some more blood.  Again, not a lot, but enough to cause me to be concerned.  My chest is also very sore.  I've got another appointment with a doctor Friday, but was wondering if I could get some advice.

I would tell you to at least get a chest xray done and see someone else, it could be a rib has pressed onto your lung causing some pain and bleeding but I am no expert so my opinion is get it checked out if you go to that Doc tell him you want an Xray done...
