From the Guidelines
The first line treatment for idiopathic foot numbness should be duloxetine 60mg daily, as it has shown consistent efficacy in treating neuropathic pain with a favorable side effect profile, as recommended by the most recent and highest quality study 1. When considering treatment options for idiopathic foot numbness, it's essential to prioritize morbidity, mortality, and quality of life as the primary outcomes.
- The treatment approach should involve a combination of pharmacological and non-pharmacological interventions.
- Duloxetine, a selective serotonin-norepinephrine reuptake inhibitor (SSNRI), is a recommended first-line treatment for neuropathic pain, including idiopathic foot numbness, due to its efficacy and relatively favorable side effect profile, as seen in studies such as 1.
- The dosage of duloxetine should be initiated at 60mg daily, as this has been shown to be effective in managing neuropathic pain, with the option to adjust as needed and tolerated, as indicated in 1 and 1.
- It's crucial to monitor patients for potential side effects, such as nausea, and adjust the treatment plan accordingly.
- Additionally, addressing lifestyle factors, such as diet, exercise, and footwear, can help alleviate symptoms and improve overall quality of life.
- Regular follow-up and reassessment of the patient's condition are necessary to ensure the treatment plan is effective and to make any necessary adjustments, as outlined in 1.

From the Research
First Line Treatment for Idiopathic Foot Numbness
- The provided studies do not directly address the first line treatment for idiopathic foot numbness. However, some studies discuss the treatment of neuropathic pain and peripheral neuropathy, which may be related to foot numbness.
- According to 2, vitamin B12 may have a therapeutic effect on painful peripheral neuropathy, but the evidence is limited to level III.
- Gabapentin is commonly used to treat neuropathic pain, and studies such as 3 and 4 demonstrate its efficacy in reducing pain intensity in patients with postherpetic neuralgia and painful diabetic neuropathy.
- The study 5 mentions that first-line drug therapy for painful diabetic peripheral neuropathy includes duloxetine, gabapentin, amitriptyline, and pregabalin, but notes that these medications do not restore sensation to affected extremities.
- In terms of guiding treatment for foot pain, the study 6 emphasizes the importance of considering a broad differential diagnosis and utilizing electrodiagnostic studies to evaluate the patient's condition.
Potential Treatment Options
- Vitamin B12 supplementation may be considered as a potential treatment option for idiopathic foot numbness, given its possible therapeutic effect on peripheral neuropathy 2.
- Gabapentin may also be considered as a treatment option, given its efficacy in reducing pain intensity in patients with neuropathic pain 3, 4.
- However, it is essential to note that the evidence for these treatment options is limited, and further research is needed to determine their effectiveness in treating idiopathic foot numbness.
