You may be experiencing what is called "restless leg syndrome".
You can also experience these sensations when you have a viral infection.
Also if there is pressure on a nerve in the lower back.
Would be a good idea see your doctor.
Best wishes.
due to exhaustion ... try taking some rest ..
Potassium is aso very good for leg issues. Eat those bananas
