As a rule of thumb pain is never normal. It's the way that your body tells you there is something wrong and you should do something about it.

Pain is what makes us pull our hand away when we touch a something hot.
Pain is what makes you limp so that you take pressure off the painful foot to protect it.

Pain is never normal.

What you should be asking is what is causing the pain? Is it something sinister or benign.

To get the answer to that question, you should see a doctor. I'm afraid no one will be able to give you a diagnosis over the internet.
