not really sure never had shin splints did you check online for more info??

Not sure, I did look and I only saw what I said, that it shouldn't have swollen lumps

Have you taken her to see a second doctor yet? If not, WHY NOT?

No, I haven't taken her yet. I will give it one more week, do you think it really is something serious? Here's a brief description, and if anyone can tell me what they think it may be, or any idea, that would be great: Pain and swelling in the inside of the lower leg, on the tibia, both legs. Sharp pains shooting up outside of left leg occasionally

Thank you so much for the help
