A very common problem that brings patients to the
podiatrists is “the ball of my foot hurts”. This symptom can have many
different etiologies. I will take the next couple of blogs to discuss what can
cause this type of pain and how it can be treated.
What causes ball of
foot pain?
Metatarsalgia, which is defined as pain in the metatarsal
region, is known as ball of foot pain. Metatarsalgia is a vague term and
therefore it is important for your physician to weed through the symptoms you have
in order to diagnose the problem. Many different things can cause metatarsalgia
such as a neuroma, stress fracture, tendonitis, capsulitis, fat pad atrophy,
gout, rheumatoid arthritis etc. I will discuss each of these disease processes
and how to treat them.
What is a neuroma and
how can it be treated?
A Morton’s neuroma, which is an enlarged nerve between the
third and fourth metatarsals, is a common cause of metatarsalgia. There is a
nerve that is “entrapped” and enlarged which sits between the metatarsal. Therefore,
shoes and activity can cause compression of the nerve and therefore can cause
symptoms. Symptoms typically include sharp, shooting pain, numbness, tingling
and burning. The most accurate way to diagnose a neuroma is with an ultrasound.
Once it is properly diagnosed usually treatment is via conservative methods. Treatment
is aimed at shrinking the size of the overgrown nerve; this includes orthotics
and corticosteroid injections. A newer treatment method is a sclerosing alcohol
injection; the function of this is to shrink the enlarged nerve. Wearing a
wider toe box can also help to relief symptoms.
If conservative treatment fails then surgical removal of the neuroma may
be indicated.
What about a stress
fracture?
A stress fracture is an incomplete fracture of the bones.
Unlike an acute traumatic fracture, this type of fracture may take a few weeks
to develop. It is usually caused by over activity and increased stress to the
bone. In the foot region the most common bone to have a stress fracture is the
2nd metatarsal. Many athletes who suddenly increase their activity
complain of pain in the ball of the foot. As a podiatrist I am on high alert
for a stress fracture in these types of patients. Within the first 10-14 days a
stress fracture will not appear on x-ray, and therefore, high clinical suspicion
is needed for accurate diagnosis. Applying a tuning fork to the area of concern
will cause pain, if there is a stress fracture. Placing a patient in a non-weight
bearing immobilizing cast is imperative for healing. Most stress fractures are
treated conservatively and do not need surgical correction.
Next week I will discuss other causes of metatarsalgia.

I just thought it may be an idea to post incase anyone else was having problems researching but I am a little unsure if I am allowed to put names and addresses on here. podiatrist
