Question 4

swollen, dry, cracked lips for 4 days now. i have tried benadryl in case it was an allergic reaction and i tried abreva in case it was a cold sore. no?

Accepted Answer

Remember the basics: Have you also been using a lip balm like vaseline or chapstick?  If your entire lips are dry and cracked, and you are feeling healthy otherwise, my first guess would be simple chapped lips.

If moisturizers are not helpful, and especially if you are having symptoms like fevers and an extremely dry mouth,  dry eyes, or other whole-body symptoms, please follow-up in person.

Question 5

can severe seasonal allergies cause cold sore on mouth

Accepted Answer

Cold sores: are caused by a virus, and come out under times of physiologic or psychologic stress, such as illness or stressful situations. Allergies do not cause them. Hope this helps!

Question 6

i have seasonal allergies right now.  developed cold sore on nose.  have cpap machine with "nasal pillows " type mask.. is it safe to use abriva .

Accepted Answer

Try a different mask: I don't think using Abreva would be a problem but that nasal pillow will severely slow healing. The CPAP company ought you provide you, on your doctor's order, a different mask which won't touch that area. 
Also, are you sure it is a cold doer and not an ulcer produced by the nasal pillow?

Question 7

3 days ago ive had itching on my left side of my lip line no burning no blisters no nothing could it be a cold sore ? its very unnoticeable when i touch its like a very small bump since we been home could it be allergies or something ?

Accepted Answer

Lip bump: A lump on the lip may be a cold sore. There are other possibilities, it should be seen by a doctor.

Question 8

i had a tiny white spot on the tip of my tongue (looked like white papilla) with white circle around it. could this be a cold sore, bacterial reaction?

Accepted Answer

No: Papillae on tongue sometimes get enlarged and sore. It's temporary and is not a viral or bacterial infection. See your doctor if it persists longer than 2 weeks.

Question 9

could a cold sore result from an abrasion on your penis after sex and oral?

Accepted Answer

Yes.: Absolutely.  It can also be either herpes 1 or 2. Barrier protection is the only protection. Have it checked, because if you have it, you are contagious to anyone you have sex with!

Question 10

when i eat ketchup, i get these cold sore like things on my lips, what am i allergic to ? fastest to get ride of them? can i use oragel if it was exp?

Accepted Answer

Cold Sore From HSV-1: Herpes simplex virus type 1 (HSV-1) is the cause of cold sores. HSV sets up shop in your ganglion neurons and  reactivates during times of stress or when your immune system takes a hit. Pain, burning, tingling, and itching often proceed outbreaks which last around 5 days. Herpes is one of the most common infections with around 90% of people worldwide effected. This is not an allergy reaction.
