Can you get a fever blister without having Herpes Simplex I?

I've been sick this whole weekend and week and developed a blister in the middle of my bottom lip. My boyfriend said I had a fever. I had a cold, sore throat, and aches on my neck and shoulders. So my question is can you get a fever blister without having Herpes Simplex I? When I search fever blister it was linked with Herpes. I do STD testing every 6 months when I go to the GYN I went about a month ago.

You don't have "herpes" in the STD sort of sense...

There are many types of herpes--Simplex 1, Simplex 2, chicken pox, and shingles. It is a virus that always stays with you...it is not a bacteria.

Oral Herpes--which most humans have--is simplex 1. The cold sore or fever blister comes out during stress or colds--i.e. fever blister or cold sore. The virus becomes active during stress or colds because your resistance is down at that time.

Genital Herpes--Simplex 2--causes sores on the genitals.

Chicken Pox-Most people get this at some point in their life.
Shingles--causes pain in an area around nerves--older people tend to get this.

I don't know of any other way to get a fever blister other than having simplex 1 or 2. However, the virus that causes oral herpes is very common, almost everyone has it and in many people it does not show up very often. In some people it shows up as a canker sore on the inside of the mouth...so people don't ever see it just feel that they ate too many crunchy chips or something.

Just don't pick at it or touch your genitals after touching your mouth--oral herpes in rare instances can be transferred to the genital area.

Herpes Simplex is just a bacteria in your system. Not to be conrfused with STD Herpes. You get it when your immune system is low. Take Euchanacia for 10 days straight and you will feel better and your blister will go away. I get them once a year and no I don't have STD. Been married to the same guy for 14 years and the only thing I can accuse him if is being a workaholic. I tend to get the blister when I am stressed out. I was told eating yogurt on a daily basis will keep that away.

Sure girlie...Herpes has many forms and simplexes! Don't take for granted that little cold sore is the benign sort. You can get simplex II, the sexual kind in your mouth too. Simplex I can be transmitted to your sexual organs and your anus....Isn't the human body woooonderful? You have to go to the clinic when you have the eruption sweetie, their not gonna find it without it...Herpes goes into the spinal cord when its dormant...Gooood luck!

yes

Well...the TRUTH & bottom line is...NO.
The reason you kept doing your searches & coming up with the same outcome is because it is true.

"Fever Blisters"...aka..."Cold Sores" ARE in fact a form of the "Herpes Simplex Virus".......keeping in mind that it is the LOWEST form, or MILDEST form.
I have been getting "Cold Sores" for many years now.
They accompany a Cold, Change Of Weather, Fever, Virus, Etc.
This is NOT the "Herpes" like "STD" herpes. It is NOT the same thing. ;)
So, you can have all the STD tests & they will continue to come up NEGATIVE. (unless you happen to contract something in between)

I trust that you will always get them now.
But again...no worries because as I said...these 2 forms of "Herpes" are NOT the same.

There are medications out there that work in "Healing" them in NO TIME FLAT!
Me, personally...I use "DENAVIR" (prescription). There are several creams out there that work in the same way.
I prefer DENAVIR because it has always worked for me.
What these creams do is "Pull Out The Sore, Thus Healing Them QUICKER" If you dont use any meds, they WILL go away, however, creams like Denavir just allow for quicker healing time. Denavir also takes the PAIN of em away.
I even had "2" At The SAME Time! :-O YIKES!

TIP: If you can get a cream like Denavir...apply a few times per day...ESPECIALLY at the ONSET of a sore. Like even when you DONT SEE one. You will ALWAYS feel one when it is coming.

So relax & dont worry. They look bad & can hurt like hell...but, you do NOT have an STD. ;)
I HOPE THIS HELPS YOU!
HAVE A WONDERFUL DAY!

remember, herpes 1 is above the belt line. herpes 2 below the belt line.

Lots of good answers except the dork that said your boyfriend is sleeping around. Herpes Simplex 1 is not the STD version. I also have this and I break out with cold sores when I am sick or also stressed out about something. When I was a child I had a cold sore for ever single school picture. I would break out the day before. Now, I mainly get them when I fell under the weather. BUT you can pass them on if you were to perform oral sex on your boyfriend while you have a cold sore.

sound like you have type 1 herpes. a fever blister is herpes/cold sore. you have all the symtoms of a first outbreak which is more severe than the following ones.
