Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that there has been ankle
sprain due to sudden twisting leading to inflammation of the soft tissues in that area and the pain and swelling is due to it..
As you are able to walk, there does not seems like any bony
fracture and mild pain and swelling is not abnormal and you need not to worry about it..
You can apply cool compresses over the ankle..
Apply
analgesic and
muscle relaxant gel over it and put ankle brace..
You can also elevate your leg while lying down..
You can also take anti inflammatory painkiller like
Ibuprofen..
Avoid excess walking and straining..
In case if it does not resolve in a week consult an Orthopedician and get evaluated..
Hope this information helps..
Thanks and regards.
