Hello,
For such kind of growths, the possibilities of epididymal cyst or spermatocele have to be ruled out. Other possibility is of a benign testicular growth. Spermatocele is a retention cyst of a tubule and is benign in nature. Usually they are left as such if not causing any symptom, but if they are causing pain, then they have to be removed. Surgery is the only mode of treatment for which I would suggest you to consult a urologist.
Regarding the testicular pain, as there is no swelling or inflammation or redness of the scrotal sacs, so the chances of epidiymitis or orchitis are rare. The other causes are testicular torsion( most common in young men), excessive bicycle riding, hernia, varicocele or kidney or ureteric stones. Please consult your doctor for a thorough evaluation, appropriate tests and further advice.
I hope it helps. Take care and regards.
The lump is getting bigger. Its not the head of my Epididimytis. almost certain this is a cyst. Help me please, somebody?
