for pain management for recovery from surgery, consider Chuchuhausi. Called 'trembling back' by brazilian cureanderos (medicine men) b/c it aids old bones, and old wounds. 
Tonic (liquid extract, dual or alcohol) form is best, rather than powder. More bioavilability. 
Watch out for interactions with chemicals from your doctor (drugs et al). 
Chuchuhuasi is a male favoring tonic. Aids in work, reduces ability of pain to get to you. 
You can take it for decades w/out negative build up or effect, but need to have vacations from it of several weeks in a year's use to boost its effects. 
For @elonmusk. Especially helpful with active, dynamic pain involving short length tendons.
