Suggest Treatment For Lower Back Pain And Numbness On Toes
Looks more related to nerve root compression from spinal stenosis.
Detailed Answer:
I read your question carefully and I understand your concern.
You make a good question as pain along the extremities with the abnormal sensations you describe can be caused both from nerve related issues as well as blood vessels issues.
When it is related to the nerves it is due to spinal stenosis causing compression of nerve roots bilaterally and leading to bilateral sciatica as that type of pain is commonly named.
When related to arteries it is due to atherosclerotic plaques in the arteries,when bilateral as in your case the aorto-iliac arteries. In most cases it happens in people with vascular risk factors for a long time such as diabetes, smoking, high blood pressure, high cholesterol. Diabetes is present in the overwhelming majority so because of you mentioning no such factors while on the other hand back issues are already known I would say neurogenic origin is much more likely and you should see a neurologist first. Probably a back MRI will be necessary.
Other telling signs are for example then when pain starts while walking (this type of pain is called claudication), in vascular claudication it is relieved soon by standing while in neurogenic claudication it is not. Neurogenic claudication can be relieved on the other hand by bending forward or when walking uphill, while walking downhill is worse.
Also in vascular issues the pulses in your feet are low and absent, I am not sure you can evaluate this yourself but your general physician can before sending you to a specialist.
I remain at your disposal for other questions.
Kind regards

Detailed Answer:
Thank you for your additional information.
As I said at such an early age usually multiple vascular risk factors are present to develop that degree of atherosclerosis, so I still think a neurogenic cause more possible.
Hopefully you will get better with physical therapy.
