[|Human|] 26 year old male with no STDs or any other health issues. Masturbated and tightly gripped the base of my penis while doing so. I gripped really hard. Before ejaculation I let go and ejaculated like normal, but felt an odd somewhat dull pressure/pain on the dorsal surface of my penile shaft about 1 inch above the base (traveling in the direction of my penis, i.e. not horizontal/diagonal). At the area of the pain was now a hardened cord with a bit of a bump at the middle of the cord. It is not visible but can be palpated. It seemed like my penis took longer to become flaccid after that. I stopped any masturbation and let it rest for a week. It seemed nearly better but masturbating very gently caused it to return somewhat. I have gone a bit more than a week without masturbation now but want to check that something like this will go away and not be any long term damage. I still feel a dull pain at the area at times when the penis is flaccid. No issues with erections or ejaculation. Is this a lymph or vein issue? Will NSAIDS help or is there anything to help with lymphatic drainage/healing? Have I done long term damage?
[|AI|]  Hello I share your concern, I will try to help you out in the best possible way. Looking at your description this could be STI or infected ulcer may be due to trauma during masturbation or an allergic reaction. I would like further information help you better relevant medical history like metabolic disease or hormonal disorderly recent exposure to unprotected sex? You should ask your doctor for few investigations to confirm the diagnosis like Urine culture and sensitivity test Blood for CBC and liver function test or urine test are advisable if it is a chronic issueNSAIDS like ibuprofen or acetaminophen will definitely help you Maintain good hygiene Wash and clean it with antiseptic solution or soapbox can apply antiseptic ointment externally. Use condom during sex if you are sexually active Hope this answers your question please feel free to ask for more clarificationThanks and regards
