What Causes Persistent Numbness On The Toes?
Neurological problems more likely.
Detailed Answer:
Hello and thanks for using HCM.
I have read your question and understand your concerns.
In my opinion, lumbar spine conditions such herniated disc disease, or degerative changes ( bone spurs for example ) that are pinching a nerve, are responsible for your symptoms more than blood supply problems.
This because of your age ( there seems to be no predisposing factors to vascular disease ), the nature of the symptoms ( numbness is primary a neurological symptom ), the distribution of numbness.
Vascular problems manifest with other signs that are visible on the skin such swelling, cold foot, etc.
Nerve entrapment syndrome also may be a possible explanation.
It is necessary to get evaluated clinically and by imaging studies in order to get a correct answer to your concerns.
Hope you found the answer helpful.
Let me know if I can assist you further.
Greetings.
