### input:
I am from Bangladesh. I am in a private service in Dhaka. I felt chest pain for last six months and so i we went a cardiologist in SQUARE Hospital in Dhaka. He gave me some test like ECG,ECHO, blood tests and ETT. All other tests except ETT was found normal. I was for 9 and half minutes in excercise tolerance test. I didn t feel bad. But the cardiologist told me that he found some significant changes in third stage of test. So, he stopped the test and he advised me to do an angiography for better result. He suspected that there may be block. Then I went to another cardiologist in National Heart foundation of Bangladesh and he advised me not to do angiography right now. He prescribed me some medicines like Anclog plus, Anzitor, Ecospirin and advised me to walk an hour every day. By this time I talked to my sister in USA. She consulted with a doctor there and the doctor said if ETT test is positive it will be better to do an angiography. Then I went to another cardiologist for third opinion. I went to Prof. Dr. Afzalur Rahman, MD (Card), Phd (card), FACC (USA), FRCP (Edin), FRCP (Glasgow), Fellow in Intervention cardiology (France & USA), awarded CRT2009. He also checked my tests and advised me to do an angiography as soon as possible to be risk free and to know the actual result. So I did Coronary angiography under him at Square hospital. My CAG report was normal. There was no blockage in heart as per result from CAG. He advised me to feel free and stopped all medicines. He told me that the cause of the pain might be from muscle strain or Gas. Still I feel chest pain and it seemed at middle of chest and sometimes from middle to left or right. I feel tired sometimes. I have my CAG report and CD with me. I need your suggestions and advice

Hi, If your Coronary Anglo report is normal than you should not worry from the cardiac point of view.  There are many causes of chest pain. Yours can be due to musculoskeletal pain or due to Costco Chat Doctor.  Both are benign conditions and can be easily treated by a painkiller. Positive ETT can be false as it has a sensitivity of around 70% but Coronary angiography is the final test and if that is normal then there is nothing to worry. So relax and don't worry about it. Hope I have answered your query. Let me know if I can assist you further. Take care
