Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that due to trauma there has been
injury to the soft tissues leading to inflammation to the tissues leading to accumulation of the inflammatory exudate in the soft tissues leading to swelling..
In case if you are able to walk well there does not seems like fractured bone..
In case if the soft tissues are inflamed and if you do excessive exertion there can be increased swelling..
I would suggest you to take anti-inflammatory painkiller like
Ibuprofen..
You can do cool compresses over the swelling 2 to 3 times a day..
You can also apply
analgesic gel over the painful and swollen area..
You can apply
Heparin gel for faster fading of the bruising..
You can also elevate your leg while lying down.
In case of no improvement in a week consult an Orthopedician and get evaluated and he can do a clinical evaluation and also advise
x ray to rue out the exact cause and treat accordingly..
Hope this information helps..
Thanks and regards.
