Thank you for consulting with Healthcare Magic.
I don't think you have to worry too much right now. Some bruises due to trauma may need some extra time to heal.
do have bruises as symptoms but they will mostly have associated symptoms like tiredness
, bleeding, recurrent infections etc.
I would advise you to wait for a week more and if not healing or further bruises appear from minor trauma consult an internist.
Please do revert with further queries.
