In many cases, however, tingling in the hands, feet, or both can be severe, episodic, or chronic. It also can accompany other symptoms. such as pain, itching, numbness, and muscle wasting.
The gravitational pull of the Moon on the Earth is about 2.0 x 1020 newtons, while the pull of the Sun on the Earth is about 3.5 x 1022 newtons.
The result of this tidal pull is a bulge in the ocean water almost inline with the position of the moon; one bulge toward the moon and one on the opposite side of the earth, away from the moon. When we observe the tides what we are actually seeing is the result of the earth rotating under this bulge.
