Hard lump below the testicle?


Hello, after a sexual encounter last November, I experienced swelling in my testicles, which caused pain when riding a bike or when touched.
For a while, I noticed blood in my ejaculate, but that eventually stopped.
One day while showering, I discovered a lump below my right testicle that was not painful to the touch and felt like it was attached to the testicle.
I later visited the urology department at Taipei Veterans General Hospital, where the doctor diagnosed me with epididymitis and prescribed antibiotics.
I was also advised to get an ultrasound, but I never went for it and did not take the medication regularly, thinking it would resolve on its own.
However, the lump has not diminished and has not caused any discomfort.
Could this be chronic epididymitis? Is it possible for the lump to persist for a lifetime with chronic epididymitis?

It sounds like it may have developed into a hydrocele.
It is advisable to see a urologist for an examination to confirm.

Chronic epididymitis is a condition that can arise from various causes, including infections, trauma, or even non-infectious factors. It is characterized by inflammation of the epididymis, which is the coiled tube located at the back of the testicle that stores and matures sperm. Your symptoms, including swelling of the testicle, pain during activities, and the presence of a lump, are indeed consistent with epididymitis.

When you mentioned that you experienced blood in your semen (hematospermia), this can sometimes occur with epididymitis due to inflammation or irritation of the reproductive tract. The fact that you have a lump that feels connected to the testicle and is not painful could suggest a few possibilities. It might be a cyst, a thickening of the epididymis due to chronic inflammation, or even a more serious condition that needs to be ruled out.

The diagnosis of chronic epididymitis often involves a thorough clinical evaluation, including a physical examination and a review of symptoms. In your case, the urologist's diagnosis of epididymitis was likely based on your symptoms and physical findings. The prescribed antibiotics are typically aimed at treating any underlying infection, which is a common cause of acute epididymitis. However, if the condition becomes chronic, the inflammation may persist even after the infection has resolved.

You mentioned that you did not follow through with the ultrasound or take the antibiotics as prescribed. This is concerning because imaging studies can help determine the nature of the lump and rule out other potential issues, such as tumors or varicoceles. Additionally, not completing the antibiotic course may lead to persistent infection or inflammation, which could contribute to the chronic nature of your symptoms.

Chronic epididymitis can indeed result in lasting changes to the epididymis, including the formation of lumps or cysts. In some cases, these changes may remain for a lifetime, especially if the inflammation was significant. However, the presence of a lump does not necessarily indicate a serious problem, particularly if it is not associated with pain or other alarming symptoms.

It is essential to follow up with your healthcare provider, especially since the lump has not resolved and you are experiencing ongoing concerns. They may recommend further evaluation, including imaging studies like an ultrasound, to assess the lump's characteristics and ensure that it is not indicative of a more serious condition.
In summary, while chronic epididymitis can lead to persistent lumps, it is crucial to have a comprehensive evaluation to rule out other potential issues. If you have not done so already, I strongly encourage you to seek medical attention to address your symptoms and ensure appropriate management. Regular follow-up with a urologist can help monitor your condition and provide guidance on any necessary treatments or interventions.
