If the bruise
has developed following injury
,it will be healed soon.
As the Glans
area(Tip) of the penis has rich blood supply,any lesion which is active may bleed.But,unless there is a big lesion,it heals spontaneously.
Regarding symptom of something else cant be concluded at this stage.
please consult your local doctor and take his opinion.
Hope it is a simple Bruise, which will heal faster.
