Morton's Neuroma Returns!

Sighh... after taking my new Nike Vomero out her maiden
LSD run last sunday, i
developed a relapse of my old
foot's nerve injury..
Morton's Neuroma!

Foot pain can be caused by injuries to the bones,
igaments, tendons, and muscles. It is also possible
to injure one or more of the nerves that course down the

When a nerve is injured, it usually results in an alteration
in sensation called parasthesia. This may feel like
'pins and needles,' numbness, or burning pain. Often, by
eliminating the cause of the irritation, these
problems will resolve. If left unattended, more serious
problems can develop. The top of the foot, the inside of the
ankle, and the toes are the areas of the foot where athletes
most commonly experience nerve problems.

A neuroma is a thickening of a nerve that usually occurs
from chronic irritation. The most common location for a
neuroma on the foot is between the third and fourth toes.
Known as a Morton's neuroma, this irritation can be caused
by repeated pressure on the ball of the foot or by abnormal foot
biomechanics, such as pronation, that causes the metatarsals
to move closer to one another.

The symptoms of a neuroma may include a burning or tingling
sensation in the ball of the foot or along the third and
fourth toes. These sensations may be decreased by removing
your shoes and massaging the area, but the pain or discomfort
usually recurs upon resuming activity.
Treatment for a Morton's neuroma initially consists
of using local injections to help reduce the inflammation.
In addition, a metatarsal pad may be placed under the foot
to help spread the metatarsals away from one another,
taking pressure off the nerve. In most cases, this
conservative care will alleviate the problem. In resistant
cases, removal of the injured nerve branch may be necessary
and can be done on an outpatient basis.
