Why would a cold sore show up now after being dormant for so long?
Q: I haven’t gotten a cold sore literally since I was about 7 I got it when I was a little, and then for years I haven’t seen one or felt one coming on till the beginning of this year. I’m now 23. I get it on the bottom left of my bottom lip, it’s small. Now I have another one. Isn’t it weird for them to be away so long and then somehow triggered to show up all of a sudden? It’s horrible. Any ideas why this might happen? I’ve used abreva and it’s helped but, I just don’t get why I’m suddenly getting them again now.
A: Your immune system could have been lowered by some thing to cause enough stress on your body to trigger a break out. Your body can suppress cold sores for years. I’m surprised you didn’t get a cold sore while you were a teenager, raging hormones can put some stress on you. Stress is a big trigger of cold sores as is being out in the sun or in cold temperatures for long periods of time. Illnesses can also bring on an out break. Use some Abreva or Lipactin and apply one of them regularly to the sore that should help make it go away faster. In the mean time don’t kiss or give any one oral sex. Cold sores are very contagious during an out break.
Will cold sores (oral herpes) show up on an STD blood test?
Q: I’m pretty sure I was recently infected with cold sores. The girl who gave them to me said she was tested recently for everything STD related, if this is true wouldn’t the cold sores have shown up on the test since they are HSV type 1?
A: If they tested for it then it would show up but any type of herpes is usually not tested for in an std test unless you have an out break of it at the time you were tested. Cold sores are also not considered to be an std, they are a slightly different strain then genital herpes but they come from the same herpes virus.50-80 percent of the world has cold sores which is usually caused by HSV1 all though not all sores on the mouth are caused by herpes.Some people who have cold sores get them when they were younger when a relative or friend with cold sores gave them a kiss on or around the mouth. You could have had an out break when you were too young to remember and never had one since, that is not too common but it does happen.
my boyfriend got a cold sore and i kissed him, how long would it be until mine would show up?
Q: my boyfriend had a cold sore and i kissed him before he knew he had it, or before it started forming (like a couple hours before) i know that i can still get the virus. if i did get the virus, how long would it be until my cold sore showed up? its been almost 48 hours since we kissed, so if i were to get it, when would it show up?
A: It’s very difficult to say. HSV is a strange virus that can just kind of come up and go away as it pleases, so nothing is really set in stone. I will say, however, that if you kissed him before it even appeared, the chances of contagion are miniscule. I would be shocked if you contracted the virus this way.
