Since last year of september I have been suffering from a sore throat, pain in my legs (mostly left leg, wet stools, ear pain, toothache and acid reflux,(causing lot of flatulence and belching). Started feeling flu like symptoms the day after I had sex with someone. Penetration was with a condom but I did oral on her. Few weeks I was having night sweats and pain in joint. Don't have night sweats anymore. Lost some weight but gain alot more after. I have not vomited. I did hiv test 4 weeks after via 4gen test, it was negative and another at 8 weeks 4gen test. Also did a rapid hiv test in december it was also negative. I did a herpes test at 3 weeks it was negative. And a hiv syphilis duo at 3 weeks as well. They all were negative. What test do you suggest I do?
