Hi, I had gone through your question and understand your concerns. Surgery is the last option and before that the right cause should be found. You need to do at least ultrasound of testicles but MRI scan or scintigraphy would be more accurate. But my opiniton is that this is siggestive of chronic epididimitis which is inflammation of part of testicle and this not uncommon in males especially in young age. This is usually treated with 10 days of antibiotics, usually ciprofloxacin and there are no permanent consequances. MAsturbation and intercourse should be avoided till pain persist, if possible since I may prolong inflammation course. Some more serious conditions such as tumors or torsion are rare but in doubtful cases you should do Doppler ultrasound or scintigraphy. Orhidectomy as an option may be considered but only if these conservative methods would be unsuccessful. Hope this answers your question. If you have additional questions or follow up questions then please do not hesitate in writing to us. I will be happy to answer your questions. Wishing you good health.
