Sounds more like an acute strain, or partial tear, of the plantar fascia, rather than the classic chronic
plantar fasciitis. This should respond to ice, stretching and rest. Try to waer a shoe with a good arch, even around the house and particularly when you get up in the morning. If the symptoms persist, there are night splints that can be utilized. In addition, platelet rich plasma injections have been very successful for the treatment of plantar fasciitis.
