Although no single treatment has shown superiority, short-term pain relief may be offered via a targeted local corticosteroid injection (CSI), used often in combination with local anesthetic (LA), which may reduce plantar fasciitis symptoms for up to 1 month. Moreover, administering a CSI is relatively quick and easy for any Provider to perform, though it is not without potential deleterious side effects and risks, including fibroblast degradation, fat pad atrophy, skin depigmentation, and even plantar fascia rupture.
Research performed in other musculoskeletal disorders (e.g. lateral epicondylitis) suggest that the "method" (i.e peppering vs single bolus deposition) of injection is more favorable than the steroid itself, though evidence for this positive effect in plantar fasciitis is rather scarce. Injection via peppering is a minimally invasive percutaneous technique which involves repeatedly fenestrating the pathologic site (i.e. plantar fascia) via hypodermic needle insertion at the tender area, then sequentially injecting a substance, withdrawing, redirecting, and reinserting all without emerging from the skin. Though hypothetical, this technique is thought to disrupt the degenerative process of Plantar Fasciitis (PF), encouraging both localized bleeding and fibroblastic proliferation and stimulating a local inflammatory response that would trigger the body's own reparative mechanism, leading to recovery.

Visual Analog Scale Score - General Heel Tenderness
A sheet of paper with a printed VAS scale will be given to the patient. The patient will be instructed to make a bold dot on the line based on how they rate their general heel pain, using the parameters listed on the scale (0 meaning no pain, 20 meaning mild pain, 50 meaning moderate pain, 80 meaning extreme pain, and 100 meaning the worst pain imaginable). Range 0-100.

Foot Function Index (FFI) Score
Questionnaire that measures pain, activity limitation, and disability in the foot. The FFI consists of 23 items grouped into three subscales: (1) Pain (9 items); (2) Disability (9 items); and (3) Activity Limitation (5 items). Each item is rated on a scale from 0-9 for the Pain and Disability subscales and 0-5 for the Activity Limitation subscale. For each subscale, scores are summed, divided by the maximum possible total for applicable items (excluding any marked "not applicable"), and multiplied by 100 to yield a percentage score from 0 to 100. Lower FFI scores indicate better foot function, while higher FFI scores reflect greater impairment.
