I can't tell you about rebounding, perse. I can tell you that plantar fascitis is caused by the plantar nerve becoming tight and possibly your achilles tendon (learned this in a class I took). Although,I cannot diagnose that to be certain. Yet I can suggest that you either see someone who can massage your feet (or if you have a Sign./Other), a reflexologist to work your reflex zones, or maybe rub your plantar nerve and back of the heel and ankle to loosen that area. Hope this helps.
