Ears for balance, solar plexus for emotional stability (dizzy - ness where no physical damage or infectionto ear) spine ( to stand up straight) and adrenals for stress of feeling dizzy and all endocrine to balance out the body.
Would treat the whole feet, natch, but also work on what came up during the treatment, sometimes with vertigo you need to work on the throat (stuck thoughts not expressed whirling in head - dizziness).
Hope this helps.
