Thank you for your medical query at AskTheDoctor.com
I understand your concern.
Yes, if there is a swelling, with a bluish skin around it, or dark skin around it, it indicates internal bleeding at the local site, and a bruise.
It is a result of an injury.
You can apply diclofenac gel 2-3 times daily till the swelling subsides.
Hope this was helpful,
