Hello,
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
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. Mondor’s disease or superficial lymphangitis also need to be ruled out.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your dermatologist. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
Thanks for the help. It's been 4 days since the last time I have masturbated and it's seeming to clear up pretty fast. I'll let you know again in about a week. I haven't applied anything to it though, so I might try that to and get back to you. Thanks!
