Cramp or Charley Horse

What is a Cramp or Charley Horse?

A muscle cramp is a sudden and involuntary shortening of your muscles, which becomes tight, known as a spasm. They can be very painful and make it hard to move, with an average cramp lasting from a few seconds to 10-minutes.

Chances are you’ve already experienced one. Cramps can be ongoing and disruptive, occuring at inopportune times like in the middle of the night while you are sleeping, or walking across the road.

What are the symptoms of a cramp?

Most muscle cramps occur in the leg muscles, primarily in the calf, and there are believed to be many potential triggers:

  • Poor blood circulation in your legs
  • Over exercising the calf muscles to the point of fatigue
  • Medications for lowering cholesterol (statins) or high blood pressure (diuretics)
  • Not drinking enough fluid (dehydration)
  • Magnesium and/or potassium deficiency
  • Aging
  • Pregnancy
  • Liver disease

How can Revitive Help?

Revitive Circulation Booster uses patented Electrical Muscle Stimulation to get the muscles in the feet and calf pumping.

By getting the muscles moving, it draws more fresh oxygenated blood into your feet and legs via the arteries while also returning the waste and carbon-dioxide back to the heart via the veins.

  • Improves circulation
  • Relieves aches and pains
  • Improves leg muscle strength and endurance

See your Doctor if your symptoms persist.
