Morton's Neuroma: a pain in the foot
When your
feet hurt, you hurt all over. Foot pain affects a person's physical
and mental well being. Simply speaking, pain in the feet can be a
real pain in the butt.
Foot pain has a way of nagging away
throughout the day. Unfortunately, almost everyone will experience a
foot problem at some point in his or her lives.
A Morton's
neuroma is one of the more common problems treated by podiatrists
today. It is one of the typical nagging, bothersome foot problems.
This foot ailment was first described by the Queen's chiropodist,
Louis Durlacher, in 1845.
This neuroma was later named after
T.G. Morton who, incidentally, was from Philadelphia. In addition to
Durlacher and Morton, many others have written about this foot
neuroma.
A Morton's neuroma is an irritated, swollen nerve
in the ball of the foot, classically described as a pain in the ball
of the foot located between the base of the third and fourth toes.
The involved nerve lies sometimes squeezed and irritated by these
adjacent metatarsal heads causing the painful neuroma to develop.
The metatarsal heads are located in the ball of the foot. This area
is already subjected to considerable pressures from shoes and
walking.
We now know from experience that a neuroma can also
develop between the second and third metatarsals. In fact, a neuroma
can develop anywhere there is a nerve. This Morton's neuroma is more
commonly a problem in females. High-heeled shoes with cramped
pointed tips cause additional pressure and irritation on these
nerves in the ball of the foot.
Individual complaints for a
neuroma vary. Frequently, a burning sensation is experienced in the
ball of the foot. Patients also complain of cramping in the foot. A
sharp pain is sometimes experienced between the bones (metatarsal
heads) at the base of the toes. This pain and sometimes a "feeling
of numbness" may involve the corresponding toes that the nerve a
supplies.
Walking in shoes aggravates pain. Often a patient
will state there is a relief after removing their shoes. Many
patients will massage their foot after removing the shoes. Less
commonly, a patient describes a sensation of "walking on a pebble"
because the inflamed, swollen nerve is felt under the ball of the
foot. A neuroma may be the result of an injury to the foot. The
traumatic event might just be the result of shoes. Most of the time
there is no recollection of any injury.
A diagnosis of
neuroma is based on the symptoms described by the patient and a good
clinical exam. Tenderness is reproduced when specific areas of the
foot are touched. Sometimes the examiner feels a mass (the neuroma).
The clinical exam will rule out other disorders, which may be
present with similar symptoms. Stress fractures, metatarsalgia,
rheumatoid arthritis, diabetic neuropathy and referred pain from the
back are just a few conditions, which cause foot pain.
Treatment begins with conservative padding and strapping of
the foot. Orthotic devices, anti-inflammatories, physical therapy,
steroid injections and the changing of shoe types are used in
treating Morton's neuroma.
In chronic cases, surgical
excision of the involved nerve mass provides the best relief from
this painful condition. Early diagnosis and treatment of the problem
will increase the success of conservative care. Neuromas as well as
other foot problems can be treated.
