Viral illness: This sounds like an unspecified viral illness. Typically cold sores come out with viral illnesses (or bacterial), but when the immune system is under stress or compromised. Your thirst could be due to fever, dehydration, or illness or a combination. Cold sores are typically herpes simplex type 1 and 80% of the population has been exposed to those. ...Read more

See allergist/immuno: It appears that you may have an immune problem and recommend that you consult an allergist/immunologist.

I have hsv-1 there was no cold sore on my mouth, and I kissed a girl with hiv+ there was a little saliva, I feel fatigue next day, can I get hiv?

Not that way: HIV has never been transmitted by kissing. We know this from the years when it was not treatable and HIV-discordant family members kiss one another. It was never transmitted except by sex or needle sharing. If things go beyond kissing, please use barrier protection; I hope she is also being treated. ...Read more

Brief supplementation with lysine 1, 000mg orally three times a day at the onset, can also hasten healing. Your physician can prescribe oral valtrex (valacyclovir). Laser treatments are also used to treat cold sores. ...Read more

Potential problem: Generally, the cold sore virus or herpes simplex virus spreads by being in the nervous system of your body. It is good practice to not touch your eyes without washing your hands first, preferably with soap and water (hand sanitizer has alcohol which can irritate or burn the sensitive tissues of the eye). Symptoms include redness, pain and blurred vision, but may not be connected to your problem. ...Read more

Have kissed someone who had a cold sore months before kissing me. Does this mean I automatically have herpes? It has been 7 weeks and no symptoms.

Had hsv1 since a child. Gave oral 2 my gf, no visible sign, felt no symptoms of a coldsore niether. 2 days later got a cold sore. Does she posb have it?

POSSIBLY: The risk of infection to a partner can be high during an outbreak, but some suggest that 95% of infected people will shed the hsv virus-even between outbreaks, while others suggest the risk is low. A cold sore is actively shedding the virus--highly contagious.

Soapbox: practice safe sex, use a condom/dam and inform your partner (s). It’s their life you may affect and infect. ...Read more

Could you contract HSV if someone licked their fingers then fingered you? No sign of cold sore noticed on mouth, and how fast would you get symptoms?

Extremely unlikely: In theory, such indirect exposure could result in transmission. But this happens very rarely, if ever. In busy STD clinics, everyone with genital herpes has had unprotected intercourse (vaginal, anal, or oral); we never see patients whose only exposure was hand-genital contact. Don't worry about it. ...Read more
