deep space medicine
N: The medical specialty devoted to the health and well-being of space aliens. Like the veterinary practice, it tends to be harder than being a general practitioner for humans because of the number of alien races involved. DSM specialists often work with problems involving eyestalks, tentacles, alien skin disorders, alien mental health, and general wellness, as well as providing alien medications which are hard to get.
My Purplonian and Martian neighbors both see Dr. Tentacleez at the deep space medicine clinic in town.
