There are two kinds of muscles – the ones that you can control like those in the arms and legs that you can use when lifting, moving, bending etc, and the ones that you can’t control. The second kind of muscle falls under the involuntary muscles category.
Your involuntary muscles (the heart being one of them) can also face spasms and cramps but the causes and results are extremely different from routine muscle cramps of limbs. In this post, we shall focus only on muscle cramps that affect our voluntary muscles.
