The cure for a strained plantar fascia involves home care measures, such as resting the feet, taking over-the-counter NSAIDs and applying ice, and medical treatments, such as corticosteroid injections, physical therapy and extracorporeal shock wave therapy, as detailed by Healthline. Doctors may recommend braces and supports to improve mobility and to prevent pain.
Applying ice to the affected area for 15 to 20 minutes up to four times each day helps ease swelling, according to Healthline, and limiting or changing regular exercise activities helps avoid putting pressure on the affected feet. Nonsteroidal anti-inflammatory drugs, such as naproxen and ibuprofen, are effective in lessening ligament inflammation. Patients can also use arch supports in the shoes to alleviate the pain.
If home measures fail, a direct corticosteroid injection to the damaged ligament can help alleviate the pain, as Healthline explains. Physical therapy allows the plantar fascia to stretch, which improves the mobility of the patient. Doctors recommend extracorporeal shock wave therapy if other methods fail. This method involves the use of sound waves to treat the strain, but it has side effects such as numbness, pain, bruises and swelling. Patients can use night splints to stretch the arch and the calf of the foot, and a boot cast can help immobilize the foot, allowing the strain to heal.
