Anyone else get red splotches after cardio?

Whenever my heart rate goes up, I notice these weird red splotches on my skin. They show up mostly on my chest and neck. It freaks me out a bit, but they usually fade after I cool down. Does this happen to anyone else? Should I be worried or is it just a normal thing? #HealthTalk #SkinQuestions #FitnessChat #Health #BodyHealth
