Need suggestions on chest pain.

Hi, For last one year I am feeling pain in both side of chest ,joint of chest and right arm after I have gone through angiography. My cardiologist told me directly dat I don't have any cardiac issue. Last month I have visited a MD he was suspecting "Costochondritis" as reason of chest pain and suggest me tests like ECG, ECHO, HRCT of chest, Xray of chest (PA view), CBC, CPK, CPK-MB, Lipid profile, Hrcrp, Vit D, Vit B12. Al the tests results came normal but still the pain is der and sometimes I feel more pain at the time of deep breathing. My doctor is out of town for next 2 months. Do I need to go for further tests for osteoarthritis or Arthritis or Rumeoid Arthritis ?? If yes please suggest me which are the tests I need to go for so that with all the test reports I can consult with you for treatment.
