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.

Sports medicine is a branch of medicine that works with athletes and others who play sports or take part in physically demanding activities that may result in injury or other overuse-related problems. Therefore, it is closely related to physical therapy. Since athletes can experience certain issues that may be uncommon in the rest of the population, the doctors who specialize in this field have advanced knowledge of the body and issues that may arise from participating in various physical activities.
