Foot massages and their impact on diabetic nerve pain (neuropathy)
Foot massage therapy has been suggested as a potential method to alleviate symptoms of diabetic neuropathy, a type of nerve damage that can occur as a complication of diabetes.
Diabetic neuropathy can affect various nerves, including those that control internal organs (autonomic neuropathy) and those in the extremities, such as the feet and hands (peripheral neuropathy). Peripheral neuropathy is a common form of diabetic neuropathy.
A 2022 study found that foot massage therapy can have a significant effect in reducing discomfort from diabetic peripheral neuropathy, while a 2020 systematic literature review suggested that massage therapy may provide pain relief, reduce symptoms of foot ulcers, and decrease hemoglobin A1C levels for some individuals with diabetic neuropathy.
Foot massage can improve blood flow, reduce pressure points, and promote tissue repair in diabetic foot disease, which involves neuropathy and poor circulation. This multimodality treatment may enhance clinical efficacy by improving hemorheology, vascular function, and patient self-management.
Massage therapy in diabetes more generally also shows potential benefits such as lowering blood glucose levels, reducing anxiety and stress, and improving sleep—factors that indirectly benefit neuropathy management. The mechanisms proposed include activation of the parasympathetic nervous system and hormonal regulation that support insulin sensitivity.
However, it's important to note that the evidence remains preliminary, and further robust clinical trials are needed to confirm these benefits and to assess safety, feasibility, and long-term outcomes specifically for diabetic foot neuropathy.
For a self-massage, a person may consider using marbles in a foot tub or bath, rolling a tennis ball on the bottom of their feet, or gently rubbing nongreasy lotion on their feet with light pressure and soft strokes. Trained massage therapists and physical therapists can provide custom treatments that target specific areas of discomfort to help relieve symptoms.
However, some important considerations and risks include the lack of high-quality, long-term clinical trial data directly assessing foot massage therapy's safety and effectiveness specifically for diabetic neuropathy. Patients with diabetic foot ulcers or severe peripheral vascular disease should approach foot massage cautiously due to risks of trauma, infection, or worsening wounds. Professional guidance is advisable, particularly to avoid pressure on fragile skin or open wounds.
Inadequate hygiene practices or use of unclean equipment during a foot massage can introduce bacteria, potentially leading to infections. Massages can increase the risk of hypoglycemia in people who take insulin to manage their diabetes. Massages should not apply excessive pressure to individuals with diabetes.
In summary, foot massage therapy appears promising for alleviating some symptoms and improving circulation in diabetic neuropathy, but further research is necessary to verify these benefits and clarify risk profiles. It is best used as part of a comprehensive management plan under professional supervision.
