Cause and plan of Treatment-In my opinion on the given data, you seem to have hematoma with resolving lump from yellow to purple in the hit area, as its 6 days past the hit you had.Treatment-would be-anti-inflammatory Voltaren gel / with Tomophobe point locally for 5 days period would resolve it.Don't guess more. I would advise ER Surgeon Consultation to avoid further complications with it. Hope this would resolve your issues. Act fast. So keep cool and Consult your ER Surgeon, if need be, who would treat it accordingly. So don't build up wrong concepts and create more psychic complications in you which would increase risks and costs to you, but just ask a query to Chat Doctor and be comfortable to resolve your health issues.
