So there is no chance that the tests were both false negatives then? the first test taken on the 2nd of December 20 days after I took the azithromycin was one given to me by a doctor at the university where you pee in the pot and fill out details and then hand it back into a doctor and they send it away, Im not sure if this test covers gonorhea as well.
The second test done on the 2nd of January was one where you go into the local GUM clinic walk in centre, again a pee in the pot type, this covered both chlamydia and gonohrea. I did not have a blood test for HIV etc as the doctor didn't think it was worth it. The doctor at the clinic did say that the previous test I had at the university would have been sent to the same place as is used at the GUM clinic so will be as reliable but I still went through with the test to make sure.
Symptoms have pretty much all gone, seem to get a slight ache when I keep thinking about it all so its probably nothing to worry about.

Having spoken to a lot of doctors I don't think I did have epidimo-orchitis, I think it was probably just epididmytis that I had for 12 days before getting treated as the testicle was not swollen and didn't hurt to touch, just the back of it was sensitive (where the epididymis is). The only symptoms were testicular pain when sitting or lying. having looked through what feels like every page on epididymitis on the internet my symptoms were not that severe and it was a relatively minor case that could have been caused by anything really, maybe another bacterial infection that could have not been chlamydia, or maybe not a bacterial infection as the case worsened with antibiotics and then had some pain after the course so it might have not even been bacterial. Would you agree that mine was a minor case of epididymitis from all the information I have given you or not?

Yea two false negatives would be highly unlikely, and as I have worn protection it is even more unlikely that I passed something to my partner as it can only be transmitted via seminal fluids. But I might suggest we go in for a routine check up to be sure, not mentioning what I have had. And yes I do think it was Epididymitis but will never really know if it was infectious or not. The doctor that examined me felt the testicle and there was no sensitivity there so diagnosed it as epididymitis, so I'm pretty sure it was just that.
The tetralysal I was taking was only 300g per day for 6 weeks is this enough to cure chlamydia or would it just coverup the chlamydia in a lab test?

Well if chlamydia can not be covered up then the tests should be accurate. The azithromycin should have cleared the infection in the first place. Am I correct in saying that there is no chance then of my girlfriend having the infection as I had protected intercourse with her 4 and a half weeks after the azithromycin, 3 weeks after starting tetralysal and one clear test a week and a half before? We have continued using protection and have not had any oral sex.
I would just like to ask that in the first consultation you mentioned that chlamydia tests sometimes struggle to pick up chlamydia if it has reached the Epididymis, is this common for it to not have picked up this? and also in my circumstances what are the chances chlamydia would not been picked up in two tests?
