Editing Plantar fasciitis (section)

===Unproven treatments===
[[Botulinum toxin]] A injections as well as similar techniques such as [[platelet-rich plasma]] injections and [[prolotherapy]] remain controversial.<ref name="Tahririan_2012"/><ref name="Lareau_2014"/><ref name="Molloy_2012"/><ref name=Monto>{{cite journal | vauthors = Monto RR | title = Platelet-rich plasma efficacy versus corticosteroid injection treatment for chronic severe plantar fasciitis | journal = Foot & Ankle International | volume = 35 | issue = 4 | pages = 313–318 | date = April 2014 | pmid = 24419823 | doi = 10.1177/1071100713519778 | s2cid = 206652513 }}</ref>

A combination of plantar fasciitis stretching and the use of botulinum toxin showed an increase in improvement and functionability in patients.<ref>{{Cite journal |last1=Elizondo-Rodriguez |first1=Jorge |last2=Araujo-Lopez |first2=Yariel |last3=Moreno-Gonzalez |first3=J.
