I have been with a questionable girl whom gave me oral sex without protection. An escort to be exact. I was with here on Thursday night. On Friday night I was with my girlfriend. Could I have infected my girlfriend as soon as (1) day. This was the only sexual contact I have had other than my girlfriend in 20 years. Is s
he at risk if I this other woman had an unoticable infection after such a short period ?

Brief Answer:
Organisms not present in body fluids for 72 hours

Detailed Answer:
Welcome to HCM.

Thanks for posting your query.

STDs are more than 30 in number. Certain STDs like gonorrhea can become infectious within few hours after the infection as it confined local area of genitals.
But infections like HIV, Hepatitis spreads through exchange of body fluids. In HIV, disease gets established only after 72 hours usually. Then only virus would be present in blood,semen or vaginal fluid. So theoretically your girl friend would not get infections that can spread through exchange of body fluids whereas STD affect local tissues of genitalia may be infectious from the hour one itself.
But Medicine is not Mathematics to get constant answers. Deviations can not be ruled out. I hope that you got the point.

Redness observed which showed up 3 days ago. No bumps sores, nothing. Just redness which is starting to disappearing today. I viewed the area thru a magnifying glass to make absolutely sure there were no very small sores or bumps. Nothing.

I know , I know, I am getting tested tomorrow. However should I worry at this point for the redness. Urin touches it at times and there is slight irritation.

Brief Answer:
Yeast or topical irritants cause redness of penis

Detailed Answer:
Welcome back.

Redness of penis may be due to either mild abrasion, or due to some applications like antiseptics or due to soaps. Yeast infection is another possibility of redness without any sore or blisters.
Consult your Dermatologist. He/she will help you in this regard.
Get well soon,

My 21 year old boyfriend was treated for chlamydia and gonorrhea about 2 days ago and still complains of stinging and itching after urination and I'm having an unusual amount of white discharge lately, no smell. What could be wrong? Could it be something other than chlamydia? Could it be warts or herpes?

I had unprotected sex 3+ weeks ago and since then have had an ongoing tingling sensation just under the head of my penis. I was tested for chlamydia and gonorrhea negative. The pain usually subsides when I sleep and comes back once I wake up. It seems the pain is mostly linked to when I am sitting. There is no burning sensation while peeing.

Well, this all started about 7-8 weeks ago. The first thing that happened was vomiting one Monday evening. It was the worst vomiting I had ever experienced. The next day, I woke up with horrible pain in my upper right flank. I went to my PCP, and she thought that it had to something with my gallbladder, so she sent me for an ultrasound of my gallbladder, right kidney, liver and pancreas. That came back fine, so she sent me to a GI to figure out why I was vomiting(about once a week) and diarrhea(three to four times daily). I had an upper and lower scope performed. I was diagnosed with Barrett s, hiatal hernia and IBS. Also, when they did the ultrasound they did find swollen lymph nodes in my colon(mesenteric adenitis). Meanwhile, this whole time I am experiencing horrible fatigue, heated face, elevated body temperature(99.5-100), pain all over my right side and back. When my GI told me that what he diagnosed me with did not explain the fatigue and low grade fever, I once again had to go back to my PCP. Let me tell you; I have been so emotional since this all started. I am crying for no reason, I feel like I have constant brain fog. So, when my PCP came into the room(she is also an OBGYN), and I begged her to make me feel better, and she pretty much told me there was nothing wrong with me, I started crying. How dare she! Anyway, back to the story. She decided to run some more blood tests and do a urine analysis. So, she said all of the blood tests came back okay. Then, today, I get a call saying there was bacteria growing in my urine, and she wanted to know what my symptoms were so she could just diagnose me with a UTI. Here s my concern: I have had several UTI s in my life, most of which traveled to my kidney. I have had Gonorrhea and Clymadia when I was 21 and naieve, but I took antibiotics and tested negative for it a later date. So, now she just wants to throw antibiotics at me, and I have been sick for almost two months. Could this just have been a UTI this whole time? Also, I do have the pain in my upper right flank as well in the pelvic area. Thank you.
