Well, Kaitlin, allow me to explain the healing process.
I don't understand what's happening in my arm.
When you broke your arm, the things in your body that carry blood, called blood vessels, burst during the break. They then swell up like a balloon and form something called a hematoma. This connects your broken bone.
After this, smaller blood vessels called capillaries start to form in this area.
Your connective tissue cells create a large group of repair tissue. This has everything that makes up the soft bone in your ear, the hard bone like your arm, and even the stuff that makes up your nails! This fills in the gap made when you broke your arm.
This then slowly being swapped with a mass of spongy bone instead. This is called the bony callus.
The cells that build and break down your bone called osteoblasts and osteoclasts, come to this area and their number starts to go up.
Those osteoclasts and osteoblasts help re-build your bone over the next weeks or months. Soon, your arm will feel like normal!
Wow! Really? That doesn't sound so bad!
It's not! You just have to wear a cast so your bone heals correctly. Hope this helped you!
