It sounds like you had an inversion sprain of your right ankle. This can affect any or all of the three main ligaments that are on that side of your foot. It is important to take care of a sprain initially and ongoing, especially if you continue to have swelling. The foot is affected a lot by gravity and fluids can accumulate down in the ankle and foot, particularly after a sprain. You should make sure to elevate your foot above your heart at least once a day - before bed is a good time. If you first try some ankle pumps - pointing and flexing the foot as tolerated - and then put ice around the ankle for 10-20 minutes while it is elevated, this should help with the swelling and inflammation.
The symptoms that you are describing can often come from pressure on nerves. This can be worse with swelling. However, you should see a doctor, one specializing in orthopaedics or neurology would be best, to evaluate you.
With any ankle sprain, it is very important to rehabilitate it well so that you do not reinjure it. As a mother of two you want to make sure that you can do all the running around that you need to do! Sometimes wearing an ankle brace for a short time and/or with certain activities can help. I would recommend seeing a physical therapist so that you can learn how to improve the strength and balance for your foot and ankle.

Make time for yourself and be sure to get medical advice regarding your issues.
