Hello, I've been getting concerned lately... Where my legs start, more-so on the insisde of both legs, their are hard lumps along the starting line of my leg... I'm not sure what this is? They don't hurt at all, and I think I've had them for ages, I've only just recently started paying attention to them... It feels like it could just be leg muscle, but I'm not too sure... Is this normal? Quite embaressing... Thank you for your help!
