An anesthesiologist is someone who anesthetizes patients. They can help sedate patients and put them under for surgeries or other medical procedures. They help prepare their patients for procedures and make sure they are not experiencing any pain or fear associated with the treatment or procedure they are undergoing. They work closely with other doctors, surgeons, and specialists to ensure that patients are being treated properly.

The subspecialty of interventional pain management aims to help patients who are suffering from all types of pain by using invasive interventions. This may include anything from nerve blocks to implantable drug delivery systems to spinal cord stimulation. This kind of treatment is often helpful for patients who have long-lasting pain that cannot be easily managed with medication or other means of pain management. Therefore, these treatments are usually reserved for those with serious pain problems.
