About a month ago I started to randomly experience slight pain and stinging on my testicles, followed by waking up one day with a huge swelling on top of one of them that was approx. another half of a testicle size on top. I saw an NHS GP who diagnosed it as epididymitis and prescribed a short 8 day course of Doxycycline, assuming that it was an infection of some kind. I used high dose Vitamin C for a few days and the swelling seemed to go down but it was still there, so I used the Doxy and it got mildly better over a week (Coincidentally my POTs seemed to get better too). But two weeks since the Abx it has been persistent in that there is slight swelling, stinging and aching - it also seems to be EMF triggered by appliances. I have now been referred to a Urologist and am a little worried, so just wondering if this has happened to anyone else or if anyone can shed some light? I have ME/CFS and also Lyme and co infections that includes some infection that could be loosely connected to causing this problem, also from my research I have found that HIV patients experience this as a consequence of immune suppression and being infected with the same coinfections that people with ME/Lyme are affected with i.e. CMV, Coxsackie etc. It is interesting as a couple of NHS GPs have had me tested for both HIV and Syphillis based on my symptoms (Both negative).
