Thank you. I will give you an update in 5 days then.
Hello,
It looks like a bruise on penis. This could be due to trauma which could have caused breakage of capillaries lying just below the surface. Do not cause any further injury till the lesion has healed, which should take about 5-7 days. The discoloration 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 spot persists then it will be best to get it evaluated from a dermatologist.
I hope it helps. Take care and please do keep me posted in case you have any additional doubts. Kind regards.
