First of all pls do not try this again as impaired blood circulation to penis can lead to multiple problems.
Do not cause any further injury till the lesion has healed, which should take about 5-7 days. The
discoloration of bruise may persist for a fortnight and change colors as the haemoglobin pigment undergoes
changes. Apply warm compresses,Neosporin ointment and calamine lotion and avoid messing with it.You can take
anti-inflammatory pain killers like ibuprofen or acetaminophen.If the symptoms persist then it will be best to
get it evaluated from a urologist. Hope it helps.Take care and regards.
