A folding table slid from another table and slammed into my ankle bon, it swelled and is very tender to touch and only mildly uncomfortable to walk on?

Ice,rest, elevate: Use ice and an ace wrap to keep down swelling and elevate it as much as possible. If it is not better in a few days you may need to get an xray. If it becomes more painful to walk on it then see a doctor and get it checked. I hope it is better soon.

NEED X-RAY: You should see a podiatrist or foot and ankle orthopedic surgeon for an x-ray. Sincerely, Dr. Latva
