Hi Jack02811. Welcome to the forum.

I'm not a doctor and I have no medical qualifications. Just 40 years of experiencing testicular pain with no apparent cause.

Epididymitis is a tongue-twister to say and I always have problems spelling it.  I've had on and off attacks of epididymitis, plus other vague testicular pains, for years. 

My experience is that a single course of antibiotics don't always clear the infection immediately - sometimes the action is delayed and sometimes more antibiotics are required.  Since the doctor has felt your testicles for lumps and found nothing untoward, there's no immediate cause for worry about cancer.  If you keep getting repeat infections or other pains, then your GP may refer you for an ultrasound scan just to check that there's nothing else going on.  I had this a few years back and it was clear, despite my long history of pains.

In your position I'd finish the antibiotics and give it a couple days to start working.  If it doesn't then contact the GP for advice.  Take paracetamol or co-codamol (max 3 days only for co-codamol!) for the pain.  If the pain gets really bad then contact the GP urgently, or if the GP isn't quickly available, ring 111.  I've had to do this on a couple of weekends when the pain has appeared out of nowhere.

Hi all I have had a pain in right testicle which started with a sharp pain but is now just a dull nuisance but can be a sharp pain from time to time  but don't know what to look for am waiting to go go for ultra sound scan  all blood tests and urine tests came back clear but am still very worried as it is uncomfortable to sit too long and not getting any definate answers to this pain.  I have had two lots of antibiotic tablets and none have worked am fedup with the discomfort and waiting for this ultrasound scan thing can anyone give me a rough idea how long I need to wait any info would be Smashing 

Hi Sweeper. 

I waited about 6 weeks for a non-urgent ultrasound of my testicles.  I was suffering from random testicle pain and repeated episodes of epididymitis.  The scan was clear. 

I've suffered from these pains, off and on, for at least 20 years.  I don't know what causes them. 

My only practical suggestion is to ensure you have adequate pain-killers to hand when the pain strikes.  This is worth discussing with your GP.
