Explanation:

Muscle cramp gets better with ingestion of potassium( it has to do with muscle physiology and how the muscle needs potassium to perform muscle actions) and we can find potassium in foods such as bananas.

Muscle strain needs heat/cold compresses and time for the muscle to recover. Rest at home should be enough.

Muscle spasm is just saying the muscle is super tired.

Eg. When you do a plank workout, your abdominal muscles will shake like crazy if you are not fit.
