I hit my hand on the corner of an iphone?

And now the bone below my thumb is protuding out more than usual. It hurts like hell too and looks swollen. What can I do? Will it go back to normal?

Step 1) make sure your iphone is okay.
step 2) is it a swelling? Is your thumb cold if yes it will become ok in a week or so
step 3) is it bluish/purplish? Go see a doctor and get an x-ray taken
step 4) increase your calcium intake
step 5) live happily ever after.

Put ice on it for first 24 hrs. If it is still swollen get it xrayed. My roomate hit another roomate with a makeup container and broke her thumb. So it could have a fracture requiring a splint
