Hello doctor,

My query is regarding sexually transmitted infection. I had unprotected sex 51 days back. I had mild fever with a very mild burning sensation on my penis for three days after that encounter. I consulted a doctor and she gave five shots of Ceftriaxone for five days. The mild burning sensation continued, but there were no warts or sores on the penis. I was negative for chlamydia and gonorrhea. The girl had colonies of candida albicans in her VDRL report. A month ago, there was a small sore on the foreskin of my penis and the very mild burning sensation was still there. I had to shift from the place because of my work and consulted a new doctor. The new doctor suspected it as herpes and gave me antivirals. That worked well for the mild feverish feeling which I used to have sometimes. I also used the cream Fucidin for the infection. However, the mild burning sensation still prevailed. I did tests for HIV, herpes, VDRL and urine routine last month, all of which were negative and normal. I consulted the previous doctor again over phone and she advised me a dose of Doxycycline for 14 days and Azithromycin for six days. I took the course and surprisingly the mild burning sensation was off. However, I started feeling a pain in my abdomen and lower abdomen. After four to five days of finishing the course, I still feel a pain in my lower abdomen (which I can feel in backside of the abdomen also). However, the infection on the penis seems to have subsided. Currently, I am taking one tablet of Azee for six days, Metrogyl three tablets a day for three days and Zocon 150 only once.

I have no rashes or any other sores or warts on my penis or my body. The foreskin was a little tight after I stopped the Doxycycline on 14th day, but nothing is there on the penis head. It was only the foreskin which troubled me and the mild burning sensation and now it seems to be fine. It is only the pain on the abdomen and lower back troubling me now. What could be the reason for the pain?



Welcome to

  • It seems that you have been tried on multiple antibiotics on just hit and run basis. Firstly, you were given Ceftriaxone for five days without getting the relevant investigations. Then you took antiviral medications followed by Doxycycline.
  • You have taken a whole load of nephrotoxic medications in a short span, without even getting the relevant investigations done.
  • You should get a renal profile, urine microscopy and urine culture along with an ultrasound abdomen done.
  • As you are having a dull aching lower abdominal pain, which was preceded by history of fever and burning sensation over penis. This is a pointer towards a urinary tract infection (UTI), which can be contracted by an unprotected sex.
  • It is not only sexually transmitted infections that are contracted by unprotected sex, but UTI are also commonly acquired by unprotected sex.
  • Notorious among STDs which are known to cause genital lesions with pain and burning sensations are candida and herpes. So, get an opinion from venereologist to rule out candida and herpes as well.
