Hello,
Thanks for the query.
Although such type of bruises tend to go away in a weeks time but sometimes,it Maty take more time,if bruise is big enough.
Accidental injuries like this can sometimes cause local pus collection or phlebitis or cellulitis.
If there is no raised swelling there or local redness and hotness there,it rules out abscess formation.
If there is no tight cord like structure there with local pain,it rules out phlebitis.
If there is no local redness along with fluid collection,it rules out cellulitis.
Presence of any of above signs requires a visit to to the doctor.
But idps there is nothing of above mentioned signs and symptoms,then you can relax,apply ice locally and wait for few days more.
In case it still doesn't resolve,even after 3 more days of icing,you are advised to consult your doctor for physical examination.
I hope it helps however you may revert to me for any further query.
Best of luck
Thanks
