Question: Hi, just today i noticed a red dot at the very base of my penis. I thought nothing of it and just scratched it and it went away for a while. Now, about two hours later it's showing again. I'm not sure if it's syphilis or just an ingrown hair. Is there a way to find that out? I also had protected sex with a girl I met at a bar exactly 3 weeks ago - and I read that the first sign of syphilis shows up after 21 days. However this is nothing like the sores on photos.

Brief Answer: Unlikely to be Syphilis,hairfolliculitis possible Detailed Answer: Hi, Welcome to XXXXXXX Thanks for posting your query. Though you had protected sex, the protection was not there for the base of penis and adjacent parts like scrotum, groin etc. Chances of STD are likely, but rare. All that glitters are not gold. Like that all sore like thing not necessarily due to Syphilis. Syphilitic sore appear any time between 10-100 days, average around 21 days. It will appear as a pappule (a raised skin thickening) and later becomes ulcer or sore and the sore will be painless and indurated (feel hard as a button). But nowadays ulcerative STD are rare and is having a remote chance in a condom uncovered area. What you had described, may be a hair folliculitis. Sorry,Photos were not found along with your question. If you consult your Dermatologist he will examine the lesion and also with investigations (if necessary) will come to a diagnosis and able to treat you better. Nothing to worry. Dr S.Murugan

Brief Answer: Notlikely Syphilis,Oralantibiotic for folliculitis Detailed Answer: Hi, Welcome back. The clarity of the picture sent by you is not very good. I am able to see some patchy red discoloration rather than a bump. Anyway I definitely feel it is not at all related to Syphilis. It may be an allergic reaction due to some local irritation or a hair folliculitis. Sometimes it will heal spontaneously. If hair folliculitis persists or spreads, then it is better to have some antibiotics for a week or 10 days along with some topical antibiotic or antiseptic creams. Antiseptic soaps also will be helpful to prevent new lesions. All these thing have to be taken with the guidance of a physician. Dr S.Murugan

Hi my daughter has Folliculitis, her dermatlogist has said.... she has been taken anitbodics for 5-6 week. It seems not to be getting better, she is Asian very senitive skin. It is on her face, both cheeks, terrible place on her chin, under her nose, a nasty place on the calve of her leg and several places on her upper shoulder. In her job she is under alot of stress, takes anit- depressive meds and very OCD. I think the later has alot to do with it. She lives away from me and is planning to visit home in the next few weeks, I m afraid this is going to leave terrible scars, she had done research on this as well... she says sometimes you have it all your life

Hi, I am 29 yrs old female. Few months back I started having skin sores mainly on my thighs and buttocks. initially I thought them to be heat boils and ignored few times. but they kept erupting one after the other continuously after which I visited a doctor who told me that it must be folliculitis and prescribed me antibiotics. after taking the medicine they subsided for a while and then started again. I visited the doctor again and advised me for blood tests for sugar. i have a family history of diabetes and the doctor wanted to rule out the same. As guessed my sugar levels were higher than normal. she advised me on total avoidance of sugar and everyday work out or atleast a walk. i followed it strictly for 2 months and then i could not make time for workout though i am avoiding sugar completely. i started getting those skin sores again with increased intensity. Am scared i might need to start taking medicines else this wont stop. i am scared to check my sugar levels again. Can you give me the possibilities and best solution.
