what causes charlie horses and muscle cramps
If a spasm is forcefully sustained and doesnât relax, then it ripens into a cramp. A charlie (charley) horse is a common term many use to indicate they either have a muscle spasm or cramp, typically in a thigh or leg muscle. This charlie of a horse is very often caused by dehydration and/or lack of potassium. A muscle spasm can occur in any muscle and you may be able to see or feel the hardened muscle, like a knot. Sometimes, muscle spasms will occur with such force that theyâll leave a bruise behind.
