Hi, a year ago I decided to do anonymous HIV and other STD's tests and I was diagnosed with syphilis. A private doctor prescribed me augmentin xr 1000 for 14 days. When one month has passed after the treatment I had another tests in other clinic and results for syphilis were negative, however I suffered some sort of urticarias, which I guess were an allergic reaction from the antibiotic and I went to see another dermatologist, who said that I still might have syphilis. I went to her clinic she made tests and confirmed that I still have it. Then I was in a clinic for 7 days, treated with ceftriaxone, one injection per day. After that I still had some sort of urticarias which show up and disappear. Several months after that I saw another doctor in different city, where I study... and I had another syphilis tests. She said that the treatment I had before was effective, but I need more injections. Again I was hospitalized for 7 days, treated with medaxone. After several months the same doctor said that she has penicillin and it is good for me to be treated with it. Then I was hospitalized again for 7 days, and the treatment was with penicillin injections which followed every six hours ( 4 injections) per day. Month after the treatment the doctor made TPH tests and said that there is no difference at all, which is strange, because I was treated with penicillin. She added that one of the tests was negative, another will stay positive for life and there is no increase, neither decrease which I didn't understand. And she wanted me to have another treatment with penicillin depo... So I don't really understand should I have another treatment, am I contagious, should I still sustain from having sex or not, am I ever gonna get cured or not...
