This study evaluates the feasibility and safety of using Lipiodol (ethiodized oil) as an investigational embolic agent for treating pain caused by plantar fasciitis. Participants will undergo a minimally invasive procedure called plantar fascia embolization (PFE) to reduce inflammation and pain in the affected area. The study aims to assess changes in pain levels, foot function, and any potential side effects over a six-month follow-up period.
