Let’s get to the bottom of whether or not a dent in your quadriceps muscle means you might have ALS.

The “quad dent” evokes fear in tens of thousands of people. Are you one of them?

Because I recognize the prevalence of how frightening this symptom is (it usually makes anxious people believing they might have ALS), I decided to write three articles on this topic.

Read all 3; they are a bit different from each other.

I’ve also included an article on dents in the calf muscle, since this location apparently is the second most cited for these mysterious dents that show up.

Wait till you find out what the most likely explanation is for this scary “symptom.”
