Many thanks for your answer. I'll take it up with doctor if i can get an appointment.
Hi,
Your problem may be due to COPD, ( Chronic Obstructive Pulmonary Disease ) which affects the lungs. Atleast in one case, I know a COPD patient was misdiagnosed and treated as a heart patient for the first time, as the symptoms may look like that of a heart patient. If you are in the construction industry, it is more likely that you have this condition. The knee pain and sole pain may be due to statin, check with your doctor, and he may reduce the dosage.
Regarding COPD, have a look at the following site:
