I have numbness in both legs below the knees. Also
A number of conditions to consider. Read below.
Hello and welcome to "Ask a Doctor " service.
I have read your query and here is my advice.
The symptoms you describe may be caused mainly by two conditions:
1- impaired blood supply to the legs ( peripheral arteritis for example )
2- peripheral neuropathy ( a condition that may be linked to underlying causes such as diabetes, alcohol use, nerves compression, low vitamin B12, drugs adverse effects, etc.)
In my opinion, there is necessary a medical examination and tests such as Doppler ultrasound, nerve conduction study, blood tests, in order to achieve a correct diagnosis.
Treatment depends on the diagnosis.
Discuss with your Doctor for these issues.
Hope you found the answer helpful.
Let me know if I can assist you further.
