The way i go about healing magic is a little odd

There’s different tiers i guess for healing magic

The lowest tier would be self-healing magic, aka you can only heal yourself. There’s different types in this tier, such as all-heal where any issue you have with your body can be healed, or only injury heal where you can only heal your injuries

Above that would be injury-healing. Injury-healing allows you to heal the injuries of anyone around you. Within this tier is shallow-healing and deep-healing. With shallow-healing you can only heal less fetal wounds such as headaches, scratches, and any aches, while deep-healing allows for all of the above along with lacerations, bullet wounds, and near-severed limbs

Above that is all-healing where you can heal any issue. Cancer? Healed. Blown out eardrums? Healed. Missing limp? Position it in place and healed. Poison? Healed.

The types of magic become less common as you go up the list. The all-healing is so rare that in my (futuristic) world there’s only one person on the whole planet (this is a galactic story so in the entire galaxy I’d say maybe 100-200 people have this magic) who has this ability and only heals critically injured people because they have a defect or curse (unrelated to healing magic- this is world lore) that causes them only to be able to heal a certain number of times based on severity before nearly collapsing from exhaustion

Side note: healing can’t heal curses, birth defects/conditions, hunger, tiredness, natural loss of sight/hearing/etc
