The commonest causes of such sensations are:Lumbar disc lesion (disc prolapse or disc degenration)
: This may be associated with pain in the back and weakness of the leg.Peripheral neuropathy
:this is due to detoriation of nerve function which occurs gradually with age.Vascular insufficiency
: Atherosclerosis of arteries, spasm, etc, may cause vascular insufficiency.
In your case, this is most likely to be Peripheral Neuropathy.
Peripheral Neuropathy occurs due to weakness of the nerves and gives rise to various sensations in the nerves. This can occur due to diabetes, thyroid
disorders, stress, anxiety, aging, etc. In your case, both your age and the fact that you have hypothyroidism
could contribute to this.
You should consult a Neurologist
for this. You may need tests like Nerve conduction tests to diagnose your condition.
