I am a married man in my early 30's with up until a year ago very good health. On December 13th 2011 i had unprotected sex with an ex coworker (who i do not have contact with anymore) i had no symptomms until January 13th -1 month, high fever, diarrhea which lasted 3 or 4 days. One week later i developed pains in my feet and ankles which progressed and i was diagnosed with reactive arthitis as a result of suspected (but not confirmed) food poisoning. My arthititic pains continued and i began to develop night sweats, loose weight and had mild testicular pain. I was prescribed naproxin for my joints which did very little and i continued to feel very unwell until the end of March when i got ill again (same fever, diarrhea etc) and was taken to A+E and stayed in hospital for a week. During the time in the hospital they tested me for a number of things and found through a stool sample that i had a campylobactor infection. I was discharged with a very strong dose of erythromyocin and booked in for a full blood test (as a precaution). I had a set of blood tests on April 12th 2012 which included HIV. All my tests returned normal with no sign of HIV. My night sweats stopped at this time and i began to put some weight back on. However at this point my testicular pain was getting worse so i went to the doctor again and he referred me to have an ultrasound on my testicles as well as an STD check for everything apart from HIV (as this was only completed the week before). Both the ultrasound and the STD check returned nothing. Meanwhile i saw an reumatologist about my joints who still believed my arthritis was a result of my campylobactor infection, she prescribed my a long course of prednislone steriods which i have been on from about June time until now. All my other symptoms have now gone but my testicles are still giving me cause for concern. They have shrunk in size and are constantly on the move. I have also had mild groin ache and my right testicle seems to be rising a lot higher in my scrotum. My wife also started having very clicky joints about 4 months ago, no other symptoms(which was the prelude to my reative arthitis)My question is, do my symptoms suggest an HIV infection? Is it possible after 4 months (i have no evidence to suggest she had HIV) would an HIV test return a negative result.
