I'm truly sorry this is happening...the first thing I can tell you is to STOP PANICKING!!! When you freak out and panic - it sends alarm bells off in kids and makes them freak out...before you know it - it will be bedlam..
I understand your panic...I really do...my son's EYEBALL hurts..Johns Hopkins cannot find ANYTHING WRONG with his EYE or EYEBALL..Am I concerned? Heck yeah? Am I freaking out over it? Nope. My son is not seeing the stress it's causing me of NOT KNOWING...he has an MRI next week (FINALLY)...but my point is - he is not freaking out because I am not freaking out.
It could be something as easy as a cyst..she could've had a splinter that she didn't know about that her body just took in and encapsulated it - that's why it doesn't hurt and that's why you can move it.
Take a deep breath - let it out slowly....DO NOT take her to an urgent care doctor...wait to see the doctor next week....it doesn't hurt her, she is not losing mobility and it hasn't changed shape or size...calm down...if I were standing in front of you - I would tell you to look at my eyes and breath - slowly in and out...it will be okay...
