Dear Lady Pta
The pain in your chest and back could be lung related, the pain on the knee could possibly be a joint or ligament problem.
Signs of lung embolism are sudden chest pain, shortness of breath, blood tinged sputum, sweating and paleness and a feeling of extreme anxiety.
The fainting spells could be due to low blood pressure or irregular heartbeat. Either way I think your doctor should re-examine you to find the exact cause of your symptoms.
