A method of treating plantar fasciitis or chronic heel spur syndrome includes inserting a first needle having a distal tip into a plantar aspect of a foot and advancing the distal tip to a location where a plantar fascia originates, and inserting a second needle having a distal tip into a medial aspect of the foot and advancing the distal tip of the second needle to the location where the plantar fascia originates. Medical imaging confirms that the distal tips of the first and second needles are located where the plantar fascia originates. After medical imaging, the second needle is removed from the foot, and a third needle having a sharpened distal tip is inserted into a medial opening formed by the second needle. The sharpened distal tip of the third needle is advanced through the medial opening to the location where the plantar fascia originates. Medical imaging confirms the location of the sharpened distal tip of the third needle. The sharpened distal tip of the third needle is used to cut the plantar fascia. After cutting the plantar fascia, the third needle is removed from the foot. A fourth needle coupled with a syringe containing a growth factor is inserted into the medial opening in the foot, and a distal tip of the fourth needle is advanced to the location where the plantar fascia originates. Medical imaging confirms the location of the distal tip of the fourth needle. The syringe coupled with the fourth needle is engaged for injecting the growth factor into the plantar fascia.
