Is this cracking at the corners of my mouth a symptom of cold sores?

Is this cracking at the corners of my mouth a symptom of cold sores?

Probably not: Cold sores--or herpes simplex reactivation--usually will present as an area at the lip red border or just beyond, that initially may sting or burn and then goes on to develop a cluster of tiny blisters. These may coalesce into one or more larger blisters and finally open. Cracking at the corners of the mouth is often from licking due to dryness (ie allergies). ...Read more

Herpes: This could be just from the small cut on your lower lip. Its difficult to say whether or not this is a cold sore (herpes actually). This can suddenly appear..even if you have never had it before. ...Read more

What are the symptoms of herpes/cold sores/canker sores on your lips/mouth?

What are the symptoms of herpes/cold sores/canker sores on your lips/mouth?

Two different things: Cankers (recurrent aphthous ulcers) are an "auto-immune" type reaction to trauma/stress (such as biting your lip). They occur on the loose membranes of your lips, cheeks and floor of the mouth. Your dentist can treat with prednisone, laser or chemicals to cut pain. Cold sores are hsv. Abreva helps those some, but most need doc rx. Both go away without treatment in 10-14 days (pain only 3-5 days). ...Read more

Should I take igm & igg blood test for Hsv if exposed to g herpes but no outbreak, have other symptoms, and had mouth cold sores in the past. Advice?

Should I take igm & igg blood test for Hsv if exposed to g herpes but no outbreak, have other symptoms, and had mouth cold sores in the past. Advice?

Depends: If the exposure is within a couple of weeks, IgM would be the test to get. On the other hand, there is no harm if getting IgG which would indicate exposure months or years ago. Unfortunately an infected person, even in the absence of symptoms,may infect other people. Until this situation has been settled, insist on condom use. ...Read more

Is a HSV igm & igg blood test helpful after g herpes exposure 6+months ago? No genital outbreak, other symptoms, but have had mouth cold sores before.

Is a HSV igm & igg blood test helpful after g herpes exposure 6+months ago? No genital outbreak, other symptoms, but have had mouth cold sores before.

Probably yes: The HSV IgG tests are excellent, and a negative result for HSV2 6+ months after exposure shows you were not infected. The HSV1 result should have been positive if your diagnosis of past cold sores is correct, but once in a while the test misses HSV1 (but rarely HSV2). The IgM result doesn't help one way or the other -- it's inherently unreliable anyway, never done by herpes or STD experts. ...Read more

I use an electric toothbrush. I get cold sores frequently. How can I sanitize my toothbrush? At $22 per head i cannot afford to replace each time.

I use an electric toothbrush. I get cold sores frequently. How can I sanitize my toothbrush? At $22 per head i cannot afford to replace each time.

Peridex (chlorhexidine gluconate): Ask your dentist to write a rxn for peridex (chlorhexidine gluconate). It is an antimicrobial mouth rinse. You can rinse your brush head in hot water , then let it soak in this for 15 - 30 minutes, then rinse again and allow to dry. Also, you might invest in 2 brush heads and alternate so they dry completely. Good luck. The cold sores are viral.If herpes, ask your dentist for rxn for acyclivir. Often helps. ...Read more

Can you get oral herpes from someone who u don't kiss but she gives u head but doesn't have any open sores or cold sores and I had no cuts on my d?

Can you get oral herpes from someone who u don't kiss but she gives u head but doesn't have any open sores or cold sores and I had no cuts on my d?

Possible but unlikel: Hi Roy. It's possible for someone to shed the herpes virus and be asymptomatic. People with oral herpes may secrete the virus 2% to 9% of the time when they are not having sores. That being said, if they are asymptomatic and secreting the virus, the amount of virus being shed is much less. You can be tested for infection. I would recommend knowing your sex partner And both of you testing for STD ...Read more
