Mighty,
Blood from your mouth?
The real issue is the cause, and whether the blood has been "coughed up" or simply "spat out".
Infection can be the main cause - do you have a history of coughing up mucky sputum? - but pure blood, especially if it is linked with pain in the chest, may indicate a blood clot. Tests are necessary to determine the actual cause.
Heart pain?
I would seek out an ECG to determine the cause of your symptoms.
This might not be the reply you wish to hear, but Mainstream are usually very good at "diagnostics" in determining the actual cause.
If you do this (and I hope you do) then let me know the diagnosis.
