Testicular Pain/Swelling

[Undisclosed1]

I am 21 years old. For the past 4-5 days I have had mild, noticable testicular pain. There is also swelling to about an extra 20% of my testicles' natural size. I also have random pains in my lower back -- left and right -- and an overall feeling of "sickness fatigue". This is accompanied by a small fever that almost vanishes 10 minutes after I drink 500ml of bottled water.

I saw a doctor and he thinks it may be chlamydia, gonorrhea or kidney stones. I have not been sexually active for over a year so I highly doubt it's an STD. I personally ruled out testicular torsion because the symptoms don't seem to match. (I hope to god it's not torsion). I have never had severe, sudden pain or anything of the sort. I also did several testicular self-exams and there are no bumps or anything that may resemble a tumor (the doctor did one on me as well and he seems to concur). There is no pain when using the bathroom, no pain shifts when moving or standing and no pain during ejaculation. No blood in the unrine, no penile discharge, etc etc. When I focus-touch the epididymis it starts to hurt a little, and can hurt a lot if I persist.

So I am confused and very worried at this point. Could my testicles be dead already in worst case scenario? Is there any way to tell right now doing a self exam? Any advice would be appreciated.

I forgot to mention the doctor also tested for hernias and he said it looked good.

There were no blood tests done, only a urinalysis which came back negative. The doctor banged each side of my back lightly and I had no pain, I assume he was checking for kidney stones. Both doctors I went to see said my epididymis was a bit tender on each testicle, and that I might have had epididymitis. How this could be makes no sense to me. Is it possible to get the tiredness/feverishness, lower back pain near my spine and around, and epididymital pain from random viral causes? If I don't have orchitis or kidney stones or STD's, then what could it be? Two swabs were done and both also came negative for STD's.

I should also mention that the abdominal pain and testicular pain have basically ended nd all that's left is a feeling of mild feverishness and flu like symptoms. I don't have a sore throat or cough though, but I feel as if my head is fatigued and I can't focus as well (similar to a cold) and am a bit more tired. Is it normal to experience these flu like symptoms even after the abdominal/testicular pain have subsided? Is it normal to still have lumps near the epididymis area that hurt lightly when touched, and will it clear up fully with more time?

How are you? Were there blood tests done? Can you tell me more about  the back pain? Were you checked for kidney stones? Testicular pain, or any pain in one or both sides of the scrotum should be taken seriously. The main causes for testicular or scrotal pain include the following: infection or inflammation such as epididymitis (inflammation of one or both epididymes), trauma or injury or torsion. Other causes to consider are: testicular tumors, hernia, pudendal nerve damage, or kidney stones.
Kidney stones may have referred pain in your testicles. Epididymitis is most often caused by a bacterial infection or by a sexually transmitted disease. It would be good to see a doctor for proper evaluation such as physical examination and blood tests or ultrasound to rule out other causes mentioned.

I hope this helps. take care and keep us posted.
