Heel pain as a result of plantar fasciitis affects an estimated two million adults in the United States every year. And over time, at least one in 10 Americans will report this common foot pain problem.
The problem may be more aptly named by calling it “plantar heel pain” because studies show there is no active inflammatory component. The tissue quit trying to self-repair long ago. Sharp pain without swelling, heat, or other signs of inflammation is the only symptom. But that pain can be very disabling affecting quality of life.
As you already know, the standard treatment for plantar fasciitis includes actively stretching the gastrocnemius and soleus (calf) muscles and passively stretching the plantar fascia (connective tissue along the bottom of the foot). Other conservative measures often used include medications and steroid injections. In severe cases that don’t respond to nonoperative treatment, surgery may be an option.
It sounds like you have benefitted from the added treatment of manual therapy. Manual therapy refers several different techniques used to release tension or trigger points in the calf. This technique is done by the therapist’s hands directly over the calf muscles.
Trigger points are irritable areas in the muscle. The area becomes tight and stiff keeping the muscle from moving (and stretching) normally. It’s that stiffness that researchers think might be responding to manual therapy along with stretching. Stretching alone doesn’t always stop the pain or alleviate the problem. In theory, until the trigger point has been released, the heel pain will continue (or come back as soon as the stretching stops).
There’s no problem with continuing to stretch your calf and plantar fascia — it will do no harm and may benefit you in the long-run. At the present time, we don’t have any long-term studies to show what would happen to patients with chronic heel pain if the trigger point is released but they don’t continue stretching.
