Hi, thanks for writing to HCM.
From the given description, I am of the opinion that the tingling
and numbness in the leg could be due to
* nerve root
irritation in the lumbar spine
occuring as a result of foraminal stenosis
* Diabetic peripheral neuropathy
So, its a double impact on your husbands nerves.
Symptomatic treatment of the tingling and numbness include -
* Daily supplementation of Neurotropic vitamins like METHYLCOBALAMINE (activated Vit B12)
* PREGALIN usage - This is basically an anticonvulsant drug used extensively to treat neuropathic pain
Consult your family physician for further management.
Hope this information is helpful. Good day
