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.”
Just what is the cause of a dent in your quadriceps muscles: atrophy? MS? ALS? or what?
Are you sick of having to inspect your leg all the time and wish you could cure this affliction and just forget about that dent in your muscle?

Dents can appear anywhere where there is muscle — this means almost anywhere on your body.
But the legs may be the most common spot where odd grooves or depressions are noticed.
The outer thigh is one specific area where many people will notice an indent or an area that caves in a little.
But it’s not on the other leg. This can cause a lot of worry. Here is an explanation for what’s likely going on.
What about the middle or center of the front of your thigh? Have you noticed any indentations or grooves there?
If your quadriceps muscle group has a dent, this is very likely benign and harmless.
Now what about the calves? In addition to being a common area for ongoing twitching, this portion of the body can also have a lot of visible indentations or grooves.
Are you so worried about this that your focus is off throughout the day?
Let’s take a look at what’s happening when calves are twitching and/or have a depressed area.
