Restless leg syndrome and pre-eclampsia leg problems seem to have many commonalities. One commonality is a tendency to an elevated BP reading - both during and after "initial" occurrence.

Both circumstance seem treatable with high-pressure deep-tissue massage as described by Dr. David Simons in his 1970's translation of early 1900's research by 12 German Research Doctors.

I would suggest as a hypothesis: Overuse in lower leg musculature causes muscle spindle cells to become overactive - causing chronic firing and shortened muscle structure - resulting in edema caused pressure which reduces capillary blood flow capacity - puts pressure on nerve tissue - and creates a chronic hyper tonus. Increased pressure causes a feed back ( possibly to Renal enervation ) which causes the heart to increase BP to provide sufficient blood flow to enable escape from a predator - but there is no predator. This would suggest why Renal nerve Ablation works in some cases. An avenue to research?

So why does treatment with Magnesium salts often ease symptoms ??
