From time to time, we all experience muscle spasms of one kind of another – this may be a twitch in our thigh, a finger, or in our lower back. These can be uncomfortable, frustrating, and disruptive to our daily routines, but are usually short-lived. More importantly, these are no clear indication of a serious health complaint.

Muscle spasms are simply involuntary contractions which can cause serious pain, particularly when afflicting the lower back – this typically happens when the spine’s facet joints are inflamed or injured, and the muscles supporting it spasm. Meanwhile, twitching in the calves, thumbs, or eyelids are common, and should stop within a couple of days.

Even if a twitch comes with a tolerable amount of pain, this can still cause upset to your work, your chores, and leave you unable to perform at maximum capacity for a while.

However, some alarming muscle spasms may be indications of a deeper underlying issue – which must be followed up on. Spasms (and, as a result, cramps) can be caused by:

  • Poor circulation in the legs
  • Calf muscles may become overexerted whilst exercising
  • Exercising in hot weather
  • A lack of effective stretching before exertion
  • Dehydration
  • A deficiency of potassium or magnesium
  • Muscle fatigue
  • A deficiency of calcium
  • Nerves malfunctioning, possibly linked to pinched nerves or injuries to the spinal cord
  • Medicinal side effects

As you can see the causes can be quite varied and they should not be ignored. A few different steps can be taken to alleviate these symptoms on your own if you do not think they are serious enough to seek medical attention.
