Anaesthetics affect different people differently, and can sometimes incapacitate people. For a quicker recovery you can take Homeopathic Phosphorus.
In cases when the body feels bruised and battered and weak, and the mind has no nervous power left, and you feel so weakened you are unable to train, try Staphysagria. It also helps greatly when there are lacerated wounds, or when you are beset with anger about the matter, or feel completely violated (as after an episiotomy).
When a surgical incision, for which you had the anaesthetic, remains very painful, you can use Arnica.
In cases where the body thermostat seems to go wrong after an anaesthetic, and you remain cold and shivery, or even ice cold, and just never return to normal body temperature, take some Homeopathic Carbo Vegetabilis.
