I think you need appropriate and prompt treatment. 
If you're interested in traditional Chinese medicine, I recommend Diuretic and Anti-inflammatory Pill. It cures epididymitis and orchitis with very remarkable effect. 
You can take it for your condition. It is very safe. In clinical cases, no allergy or side effect has been found yet.
