What is a Neuroma?
A neuroma is the disorganised growth of nerve tissue from an injured nerve. This forms because of the body’s attempt to heal the nerve injury. Unfortunately, this can lead to neuromas becoming very painful with associated functional loss. On the other hand, however, they can remain completely pain-free.
What causes a Neuroma?
Neuromas, often referred to as digital neuromas in fingers, can occur from a partial or complete disruption of the nerve. This may include a cut or crush injury to the nerve. Neuromas can even occur after surgery, especially after a finger amputation.
Symptoms
• Pain:
o Varies widely- sharp, electric, shooting, burning
o Worse with direct pressure
• Altered sensation:
o May feel like numbness, pins and needles
• Swelling:
o Leads to a sense of fullness in the finger
• Sensation of a Lump:
o Feeling like there is a pebble or extra bone growth
Conservative management
Conservative management of neuromas can alleviate symptoms and improve function. By making modifications to activities and engaging in hand therapy many individuals can successfully manage their condition without the need for surgery.
Some treatment modalities that are used in hand therapy are splinting, nerve desensitization, gentle scar massage, high frequency electrical stimulation, gentle nerve mobilisations and progressive strengthening.
If conservative measures are not enough, consulting with a specialist can help determine the next best course of action.
