What Is the SX Medical Abbreviation Meaning?

The abbreviation is for the word symptoms. If you see it written “s/sx” it is the shortened term for “signs and symptoms” of a certain condition or disease.

You will notice how the letter “x” is used after the first letter of each, which makes charting and documentation even faster for busy medical professionals.
