Question: I am having constant pain in my tail bone since last 1 year. I am also having persistent balanitis since last 1 yr. I got my STD tests carried out for HSV1, HSV2, Syphillis, and HIV also. I am enclosing the report for the same. As it can be seen, all tests were negative. However, I feel that I have contracted HSV2 infection as i had oral as well as protected sex with a casual acquaintaince in March 2010, three months after which I developed 4 to 5 pimple like small boils (without water or pus inside) in my groin area including lower half of the penis. They cleared up in about four weeks time on their own. Subsequently in August 2012, I suddenly developed two small chanchre sores just below the glans of my penis which went away on its own after about a week and have not occurred again since then. On being advised by a Doctor friend, I took a 14 day antibiotic course of Doxycycline 100mg (twice a day). I contracted Balanitis about an year back and it keeps on recurring on and off. I have had anti-fungal medication and also apply Clotrimazole cream and soframycin topically over the effected area of my penis.I am otherwise a healthy 41 year old male with all blood parameters within healthy limits. Please diagnose my conditionand help me with the treatment for balanitis and constant mild to severe pain in my coccyx (tail bone).
