DermTV The Difference Between Canker Sores and Herpes DermTV Epi 103
Hello, I'm Neal Schultz pause and welcome to DermTV. When we get sores inside our mouth or on ourlips, usually they're very painful. And almost all of them are causedby one of two thingsâ€”either a herpes virus outbreak or canker sores, andI find that not only do most people get them confused, but can you believethis, most s get them confused also. So let's talk about it.
Canker sores are not contagious. They'revery painful, especially when you're eating and food touches the areawhere you have the canker sore. Canker sores occur almost exclusively insideyou mouth, not outside, not on your outer lip, and not on your chin. Andwhen they occur inside your mouth, which can be on this part of the skinor seen inside the cheeks, you see a gray or tan, round area with a brightred rim right around it. They go away in a couple of days and they'reeasily treated with topical antibiotics. Usually, we take tetracycline,open a capsule, put it in a
little glass of water, and take just a pieceof cotton, dip it in that water, and hold it against the canker sorefor a few minutes and, after 2 of 3 days, it will go away. This is very,very different from herpes outbreaks. Herpes outbreaks usually are notthat painful although right before you get them, you feel a tingling ora burning in the skin where you're going to get the outbreak. They arevery contagious. They usually don't occur inside your mouth, they occuroutside your mouth. They can be right on the lip, on the edge of the lip,or around the mouth, or really
any place on your face. And when they happen,usually they occur with blisters, and those blisters are often clusteredtogether and with a red ear around it but not a red, sharp rim likeyou see with a canker sore. Over a period of a couple of days, they dryand crust and scab. They're very easy to treat. They're treated withoral medication, oral medication for only a day may become not contagious bythe second or third day. If you're getting sore inside your mouth oraround your mouth or on your lips, and you're not sure what it is and you don'tknow how to treat it, see your
dermatologist who can give you some medicineto make sure that the sores go away faster and you become comfortable muchsooner.
DermTV How to Heal Cracked Fingertips DermTV Epi 125
Hello, I'm Neal Schultz pause and welcome to DermTV. Fingertip cracks are so, so painful but theyare amazingly easy to fix, and they are easy to fix with stuff you alreadyhave in your medicine cabinet, stuff like BandAids and practically any ointmentlike Vaseline, petroleum jelly, Aquaphor or even the antibiotic ointmentswe talk about like bacitracin and Polysporin and, as crazy asthis may sound, if you catch
that crack real early, Krazy Glue will fixit. In order for you to understand why these things work, you needto understand what's going on here and what causes them. So I'm goingto explain three different facts. First of all, the skin of the tip of yourfinger is very thick, just like the skin of the palm. Second, any time fluidcomes into something, it gets larger, just like when you sprain your ankle.The ankle swells up because of all of the fluid that comes in to helpheal it and, on the other hand, when you lose fluid from something, it shrinksand shrivels. That's how a
grape goes to a raisin. And third, in thewintertime, the temperature is lower, the humidity is lower and there ismuch more evaporation of water from all parts of our skin. So, let's start with this representing thecurve of the tip of your finger and the thickened skin. You can see this littleline. This line represents a crack. That crack can come from a simplescratch, just over drying of the skin or any other trauma that happens to theskin. But you get a crack. The surface of that crack then loses some waterby evaporation. Because the
skin is so thick, there is more water beinglost at the top than at the bottom. As a result, the crack starts to open.Well, now the inner part of the skin is exposed so the fluid, becauseof the lower temperature and humidity, can evaporate from there and, asit evaporates, it pulls a raisin deal on us, it shrivels up, so the inner partsof this crack shrivel up and pull apart from each other and they keep pullingfurther apart as more and more water is lost. It's a little bit likea positive feedback cycle because, as you lose more water, it opensup more, it exposes more of that
inner skin but look at what else is happening,it's getting deeper and, as it gets deeper, it starts to hit nerve fibersand that's why it's so painful. So how do you fix thisé Just stopthe leak, and we stop the leak of that inner fluid by putting bacitracinor Polysporin or any of those other ointments I mentioned right into thecrack and then covering it with a BandAid. The BandAid and the ointmentprevent the natural fluids inside from evaporating. As a result, the fluid accumulatesinside and, as it accumulates, it causes swelling of the innerwalls of the crack and,s as
they swell, they move closer and closer togetheruntil they touch each other. It becomes less deep, less painfuland, as a result of the two sides coming together, it actually heals. This processonly takes 24 days of using your ointment and BandAids 247 forit to actually heal. And the reason you can't use Krazy Glue when it'sdeep and open like this is the Krazy Glue will go in too deep and it willhurt but if you use the Krazy Glue at the very beginning, it won't hurtand it can seal it just the way the BandAid and ointment does. So the nexttime you get a painful
