Start with Massage Tutorial: Reflexology basics, techniques, & routine (19 min, Massage Sloth), then Myofascial release for "that damn spot" (upper back/shoulder pain) (25 min, Massage Sloth). All 416 lessons here are free, from the teachers' own official uploads. You'll need portable massage table, massage oil, table sheets set and a few more basics (about $215 of kit). The book to keep beside you: Trail Guide to the Body by Andrew Biel.
