How long after the by-pass surgery you had no chest pain ? Have you done any medical heart investigations after the by-pass surgery?
Do you suffer from high blood pressure, diabetes, high cholesterol... and do you smoke?

quit smoking after heart attack 11/1/05 do not have high col, do not have diabetes blood pressure high norm stress test ok did have stint put un upper left 9/07 but aches were all ready there the more tired i get the more it hurts and my scar swells up and turn dark red

If the chest pain and tiredness continue to persists you may need to to do coronarography to investigate if those stint and by-pass are blocked again or there are new blockages on some other heart arteries. If coronarography is OK like the stress-test then the pain probably doesn't origin from the heart.
You can consult some cardiologist about your condition.

they just ran tests heart is up to par but i think i may have confused you its the chest wall and tissue the center of the sternum outward aprox 3 inches the bone for lack of better word is raised by the incision 3/4 to1/2 inch all the way down to the end of the incision it aches burns ect is this normal i take tylonal for it

Is there any swelling, redness, discharge or pain coming from the scar?

swelling and the scar tightens turns red the more tired i get

You might have some local infection on the skin above the sternum. You can consult your primary health provider to confirm or rule out this assumption.
