Is Canker Sore a Herpes Symptom?

Recently, I received a question from one of our readers: Is canker sore a symptom of herpes?
Just based on this single statement I knew that she was mixing up with canker sore and herpes. Then, I thought as a layman, many people might be getting confused with these two disorders, and today I decided to write a short article covering these topics.

Even though these disorders usually affect oral area, there is a vast difference between them. Lets talk about them one by one briefly. Canker sore is a common disorder affecting millions of people all over the world. An alternative name for canker sore is aphthous ulcer and is used synonymously. Canker sores are usually oval or round in shape with yellowish or whitish center and has red border. They are usually inside the oral cavity on your tongue, gum and inner side of lip or cheeks, but never on the surface of  your lip or corner of your mouth. Sometimes, tingling and burning can be associated with it. Occasionally you may also have fever and lymph node enlargement. There are different types of canker such as minor, major, and herpetiform, but the most common one is minor which has oval shape and heals without scaring in couple of weeks. The good thing is that in many cases no special treatment is required and most people recover from it without any complication in 1-2 weeks. It is worth noting that cancer sores are not contagious.

On the other hand, the word herpes scares most people even though oral herpes is not a sexually transmitted disease. Oral herpes is so common that most of us might have encountered it or would certainly encounter in our lifetime. Oral herpes is also known as fever blisters, cold sore. In contrast to canker sores, herpes usually affect your mouth, lips and other surrounding skin, but in some cases it can also appear inside your mouth. Herpes is contagious and can be transmitted to others very easily by skin to skin contact or kissing. They usually present with tingling, pain and itching followed by painful fluid filled blisters; these blisters rupture and become sore and ultimately heal without any treatment. The outbreak may usually range from 1-2 weeks. Just keep in mind that the risk of transmitting infection is very high during active oral outbreaks as compared to asymptomatic phase. It is also important to note that at present there is no cure for herpes, which means that infected virus will stay in your body forever just to cause recurrent outbreaks in future.

I think by now many people might differentiate canker sores from oral herpes. The aim of the article is to make you aware of these two disorders which may have similar overlapping symptoms. An ability to differentiate these two conditions would also put your mind at rest and avoid all those hassles for doctor visit.

Am I pregnant? Accuracy of Pregnancy Tests

Pregnancy is one of the biggest events in women's life, but unwanted pregnancy and its consequences are totally different than desired pregnancy. One of the most important question that every women has after unprotected sex is: am I at a risk of pregnancy? They will explore all sources of information including internet, forums, friends, and close relatives with a hope to find an answer. The reliability of the information provided by these sources cannot substitute the physician visit.

Today I am going to talk about a different scenario which possesses a risk for pregnancy and how can you confirm or rule out pregnancy. I believe that knowledge is the most powerful tool to reduce your stress. Just for your information, an unprotected sexual exposure has the biggest risk of pregnancy, but it is not a rule to get pregnant like that. A successful conception requires an unprotected sexual exposure at the time of ovulation, healthy motile sperm, favorable environment for sperm in female genital tract,  sperm compatibility, and many other factors. Problems in any of these factors may interfere with conception. Just keep in mind that adequate amount of sperm needs to be deposited inside genital tract to become pregnant. Thus, touching/ genital manipulation, sexual act while wearing undergarment, or presence of sperms in fingers practically does not poses any risk of pregnancy.  Moreover, pregnancy from these kind of sexual exposure is rare and not well documented. So you can ease your mind, if you had low risk exposure. Another important factor is timing of sexual exposure, if you have regular monthly period and your sexual exposure is within safe period, you are most likely in safer side.

Our next important issue is an accuracy of pregnancy test. We all know the there are tons of different brands out there in the market. I am sure many of us knew that there are two different kind of pregnancy test such as urine pregnancy test and blood pregnancy test. Home pregnancy test (HPT) is an urine based test and you can buy the kit from over the counter whereas for blood pregnancy test you will have to visit a clinic to run the test. HPT is much easier, cheaper and faster than blood pregnancy test, but the drawback is that it is not 100% reliable. In general accuracy of HPT may range from 97-99% depending upon the brand.

It is generally recommended to do HPT after your period due date, if tested negative, repeat the HPT again after two weeks. Getting negative HPT two weeks after period due date is very reliable and rule out pregnancy in most of the cases. However, if you are having pregnancy symptoms, it is still better to go for blood pregnancy test. You can read more about this topic from this link, click here.
