My friend has been suffering from chest pain while breathing since 5-6 months including indigestion and gas problems.Two months ago he was diagnosed with hypertension and was prescribed TELVAS 40 daily. Recently his general practitioner told him to do some test like LFT, RFT, CBC, Thyroid,All reports came normal except RFT with abnormal results and haemoglobin -9.5 Is something serious for him?
