3. A skin rash
Dermatitis, or a rash, can be the result of a number of health conditions, such as allergies, an autoimmune deficiency, or mono. If you are infected with mono, a skin rash may appear on various parts of the body, but it is most likely to affect the arms and torso. The rash can appear pink in color and have an appearance similar to that of measles.
It can be extremely itchy and even painful, as you might experience a burning sensation. Dermatitis is one of the ways your body fights an infection. While not everyone who has mono will develop this symptom, if you notice that you have developed one and have other mono-like symptoms, it’s important to check in with a doctor.
