Hi, There are several types of angina. The common form is usually felt when the heart is working harder - esp. during strong exercise when more oxygen-rich blood has to be pumped to the muscles. The overall feeling is heaviness across the chest, leading to an uncomfortable pressure sensation. With continuing activity this becomes mild pain then strong pain and a feeling that your chest will explode. This is a
danger point where an affected part the heart muscle can fail and a heart attack result.
Often the pain radiates from the chest into the arm, lower chest, neck and back. Importantly, abruptly stopping the exercise leads to a quick recovery. Medications (esp nitrates), taken as patches, tablets, or sprays can rapidly dilate the cardiovascular arteries and also provide quick relief.
Other, more dangerous forms of angina can strike at random times, and sometimes the restricted blood flow around the heart can occur with little or no pain or warning sign, but with the same serious consequences. Quite a high proportion of those suffering heart attacks do so without experiencing angina or any other warning signs.
With your history it's most important to get a careful and thorough diagnosis.
All I can say is that lower levels of angina are not usually that painful but more of a sensation of pressure or tightness.
Hope this helps a bit.
