I have been having unprotected sex with my partner for 3 months now. Last week tuesday, a day after the last time we did it, I fell sick. My body was too cold and a had a very painful headache the whole week. It would get worse when I stood up or got out of bed. I also got a sty on my eye. I tried to make it disappear by holding a cloth with warm water against it but it just kept on growing. Its been exactly 7 days now. I also had a small pimple on my right testicle. At first I thought it was an ingrown hair but after a day it turned into an open sore. It hurts really bad and I can't really walk cause I hurt myself. I went to see the Dr and he said it might be syphilis. He injected me and gave me some tablets. But only the headache has gone. The sty and the open sore are getting worse. My partner has no symptoms or anything unusual and she claims to have never cheated. This just made me more confused. Please help. What could it be?
