Hi, I am an American Board Certified Neurologist with vast experience in diagnosing & treating all types of neurological & other medical conditions including the concerns of “Pain medications, and Angina pain” you have mentioned here and I am very glad to help you with your health concerns.
To your first question, “what is dilaudid and what is it used for?”
Dilaudid is the brand name for medication Hydromorphone
This medication is an example for narcotic pain killer, it is also called as opioid pain killer
This is used to control moderate to severe pain due to various reasons.
To your other question “what is heart angina?”this is sudden onset of chest pain due to sudden compromise in the blood flow to the heart. This usually happens due to narrowing of the arteries supplying the heart and the sudden reduced blood flow causes reduced availability of oxygen and other nutrients to the heart and this causes chest pain (and sometimes other symptoms too like sweating, lightheadedness etc along with chest pain).
