pictures would be nice.
Is there any pain?

If the dent is getting bigger and bigger I'd see the doc.. But for all I know you're just getting more defined and the dent is just a natural separation between two muscles..

i too have a dent in my upper quad muscle that i have been concerned about. it has been there for several years (can't remember for sure when i first noticed it). i have excercised (step aerobics) since i was 23 and i am now 53. recently i have started doing more on an elliptical and the dent has gotten more pronounced (which must be from the build up of that muscle). i had an MRI done and they said there was nothing there but "minimal scarring". my doctor wants to do a biopsy of the area because he has no clue what it is and after reading these posts, i'm not sure i need to do that. has anyone ever figured out what the dent in the leg is? it doesn't hurt in any way. i just don't want to overlook a possible problem...t

Well, I didn't expect to find so many people with the same thing.

Last year I was sick with stomach problems, was very sedentary and lost weight, about 20 pounds. Now that I've gained it back, I'm have much less muscle. I'm assuming that this is my new fat deposit due to atrophy, but it's such an obvious "DENT". The left side is worse than the right. I've had hip pain in the left side and have been seeing a chiropractor. It's helping and I'm working on getting my leg strength back through lunges.

I was doing some balance excercise that involved lifting my leg out in front. That definitely works the upper thigh area. Still doesn't make sense since my thighs used to have much more muscle over-all.

I have been taking HCL to help with stomach problems. Someone mentioned some training supplement that contained HCL as well might cause fat deposits.

Oh my gosh! Finally, I've found someone to describe the EXACT problem I have. I've been searching online where it describes a dent on the thigh, seeming like "a split between the muscle", but could never find it. The dent doesn't hurt, but it gets really uncomfortable at times, not to mention it's very noticeable. I also feel a little pain, like tightening of the skin when I pull my leg backward, and there is a SUPER noticeable dent that appears. If I pour water into that dent, it would hold. That's how deep the dent is. The skin at the affected area is also very thin, and I can realy stretch it, fold it. I'm not an athelete or anything and have never injured my leg. I'm just a normal girl who weighs 110 lb. And I'm just moderately active. I remember first noticing the dent when I was around 10 because the pants fitted differently on my left thigh than my right one. I also noticed it's gotten a bit bigger and more noticeable. It REALLY aggrevates me. If anyone knows what this is or how to fix it, PLEASE tell me. I feel that if I go to see a doctor, it'd be useless.

PS: Thanks for taking time to read!

INDENTATION IN OUTER LEFT THIGH - HealthBoards Message Boards theres a lot of replies there with people having the same problem. a lot are saying its atrophy fat, nothing to worry about (unless there is pain).

Ok so I pretty much just registered so I could post on here about this. I too googled 'leg dent' and got this forum, and I've finally figured it out!
I just moved into Halls of Residence at university. I've been using the free gym and running a lot, and I was quite happy with myself, until I noticed these two horizontal dents in the fronts of both thighs and the exact same spot on both legs. I figured it was a muscle forming funny because I was running, but I was confused because I used to run a lot and never had it before. It started to get worse though, and I got really self conscious. You can even see it through pants! So I tried to stop running for a month and nothing changed.
Long story short, I read that someone said they got their dents from leaning on something all the time. Well guess what, the vanity in my new room has a low shelf which lines up PERFECTLY with both dents, and I'm always leaning on there like an hour a day drying my hair and doing my makeup! how strange is it that you can alter your physique from leaning on something? I'm now convinced that's what it is because it makes so much sense. I will stop leaning on it and update in a month. My advice is also to look around and see if anything fits in your dent!! Trust me, mine are huge and deep I never would have guessed

I had to join just to try and figure this out. I developed a dent on each thigh a few months ago. I have recently been trying to lose weight. I have never been a runner but for the past few months I have been running and that is when I noticed the dents. Also I noticed that my fat seems to be changing and distributing itself differently than when I was younger. I am 35 and now am at 150 pounds, I wear a size 8 so I am not a huge person but my thighs are terrible looking the older I get. I couldn't see cellulite before but now I can. I did the desk/table test and not only do my dents match perfectly to my desk which I do lean up against for some periods of time but since I gained weight and my pants are a little tight, my pants crease right where the dents are when I sit at my computer which I have been doing a lot of. I dont know if all this is the reason for the dents but i think we can figure this out. Also recently I have been taking vitamins C,E,D,Lysine, Folic acid, calcium-Mg-Zn, Fish oil everyday-which I didnt do before. Does anyone else have bakers cysts, bulge on the backside of the knee?

I have a left upper thigh leg dent. It is just horrible looking. I worked out pretty regularly for years and then started night school, so the working out had to go. I still try to do squats and lunges when I can. I have had my leg dent for a little over a year. My right leg is fine. It actually appears like my muscle has fallen or something like that. I am hoping that it will just go away like someone mentioned. I will also check the leaning up against something and see if there is something there. I am about 5' 6" and weight 120, which is the most I have weighed other than at delivery of my 4 kids. My top weight was 150 at delivery so I have never been extremely over weight or anything. It is just plain strange and I hope it will go away. I took my 10 year old to a baseball game tonight and the dent is aching. The aching only seems to happen during weather changes. I have not noticed any change in the dent, it is just there and ugly.

If anyone every gets a good answer about this it would be awesome! I was thinking maybe a doctor could go in and re-connect my muscle the way it is supposed to look.

I like how all these "I have a dent" posts are people with 1 post. Funny how nobody else who have been here a bit have it happen to them.

I found this forum because I too have a dent in my right thigh.It appeared a couple of months ago and has me very puzzled.I'm 59 years old,110 pounds and work out at home.I take good care of myself.This is probably more common than we think ,people just don't talk about it.Are our muscles just plain tired?

they could all be one person messing with us.
But unless someone actually posts any pics, we have no way of figuring this out. So if you're worried about it, go see the doc.. and for the love of god, post some damn pics.. I wanna see what all the fuzz is about.
