Should I be worried about my bicep?

On the inside of my biceps, right under my armpit, I have a jagged looking part before my bicep starts, maybe it's called the cut of the bicep?

Anyway, one of these jagged parts might be getting lower, but I don't feel any paine in it, should I worry?

Anyone know what I'm talking about?

For people to be able to help you better you should post a picture of the problem so that we can get a better idea of the problem.

Alright, I'm a little embarrassed to show my muscle because I'm so skinney, but hey this isn't a bodybuilding site, so here I go! lol

I don't see anything. It looks like normal biceps.

In that pic I posted it's hard to see the area I'm talking aboutThe area with the red line is where the jagged part is. I have it on my other arm too, but on this arm it's lower.

You have less fat on your biceps, then before. Your biceps is just more detailed.

Alright, I wasn't sure if I should go lighter on my training. Thanks for the help!
