Brief Answer:
Varicose veins a possible cause.

Detailed Answer:
I read your question carefully and I understand your concern.

That type of symptoms could be cause be two main issues, a peripheral nerve involvement or a vascular problem.
As for a vascular issue it could be in the setting of blood vessel blockage. It could be an artery occlusion or narrowing or a vein issue such as thrombosis or varicose veins. The symptoms you describe with the accompanying would correspond more to a vein issue. Varicose veins are the most common cause and would explain all of your symptoms. If there is also swelling of the limb and local temperature (higher temperature on touch than the other extremity) then it should be looked right away as it might indicate a deep vein thrombosis which requires urgent treatment.
An arterial occlusion or narrowing would be accompanied by pallor, coldness of the limb, lowered pulses, pain, doesn't look likely to be your case.
A peripheral nervous system issue may involve the nerve root in the spine due to disc herniation or degenerative spinal changes (but usually there is some degree of back pain as well), or a more peripheral nerve involvement due to nerve compression or damage to the nerve by other factors such as diabetes. Nerve involvement would manifest abnormal sensations and tingling, pain in the area supplied by that nerve. If you had provided some more details on the precise location of the symptoms, their onset and evolution in time, other conditions you have it might be useful to say something more.

I remain at your disposal for other questions.
