Dear doctor, In last 7-8 months i m suffering from shortness of breath with mild pain in left side of chest specially in morning or evening time. 8 months back for the same reason i visited a doctor and he advised to get ecg, lipid, cbc, xray. Everything was normal except the LDL cholesterol was a bit higher side so he said that i have a problem with my respiratory system and prescribed with few medicine and i was normal then. Now again the same problem i m facing. My physical activity is very less and sitting office in 10-12 hrs. Am i suffering from any heart problem or something else. Kindly advise.
