The duration of pain associated with plantar fasciitis varies from person to person. During the acute phase, severe pain may last for one to two weeks. If physical therapy and oral medication are promptly applied, the intensity of the pain can be significantly reduced, generally seeing improvement and relief after about 3 to 7 days. If the pain does not show significant improvement after more than three days of the above treatment, local trigger point injections can be considered, typically once a week for a total of 2 to 4 sessions, which can also yield good pain relief results. However, it is still advisable to avoid excessive weight-bearing activities afterwards to prevent recurrence.
