Non-surgical activities are the first treatment for plantar fasciitis. Plantar fasciitis may be worse after certain exercise, such as running on hard surfaces. Stopping those activities can help it heal.

Icing the bottom of your foot by running your foot over a cold or frozen water bottle can be helpful at reducing the inflammation. Non-steroidal anti-inflammatory drugs (NSAIDs) can also help, as can steroid injections by a physician.

Stretches for your feet and calves so the muscles aren't tight is the best way to help treat plantar fasciitis. 

Wearing supportive shoes and night splints and doing physical therapy are also helpful.

If non-surgical treatment doesn't help, surgical procedures are available. One option is to lengthen a calf muscle and another option is to partially cut the plantar fascia ligament. Your doctor will discuss if surgery is right for you.
