I have the first stage of syphilis. I came to know about this last month. From the past three weeks, I am under treatment and taking Doxycycline 100 mg capsule twice a day. I took this medication for 15 days. Yesterday, I had a blood test done for VDRL (Venereal Disease research Laboratory) and my value is reactive (1:4). Also, the ulcer on my penis head has not yet healed. I was asked to apply povidone-iodine 10 % ointment on the ulcer. Should I go for Penicillin treatment? I got tested for HIV1 and 2 tests (Human Immunodeficiency Virus) and CMIA (Chemiluminescence Microparticle Immunoassay)a month back with a value of 0.15 and before ten days, the value was 0.13. Currently, I am consulting a dermatologist. Should I switch to sexologist for syphilis treatment? Also, please suggest what diet should I follow to overcome this disease?
