CONDUCTION PAIN
This usually occurs when a nerve has been damaged due to trauma, entrapment or demyelination. The regenerating nerve is often extremely sensitive to norepinephrine.
TREATMENT CONDUCTION PAIN
Oral Medications: Most medications are ineffective for this type of pain.
Anticonvulsants such as gabapentin or sodium channel blockers such as mexilitine can be trialed.
Topical Medications: Emla or capsaicin cream may be useful in desensitizing the regenerating nerves. An aspirin salve made by dissolving 3-4 soluble aspirins in alcohol and dabbing on the skin can produce a decrease in pain within 30 minutes. If successful the salve can be repeated every 3-6 hours.
Injections: Injection into a presumed neuroma which removes the pain may indicate that the site of the neuroma is accessible to either neurolytic therapy or surgical removal The neuroma should be injected on at least two occasions, with satisfactory results, before neurolytic therapy is undertaken.
