Brief Answer:

Detailed Answer:

Skin lesions that look like blisters are usually caused by viruses in the herpes family. If the lesions are around the mouth, most commonly they are caused by the herpes simplex virus which can cause cold sores. If they are in a patch on another part of the body, it can be shingles, which is reactivation of the chicken pox virus - herpes varicella zoster.

Herpes virus lesions typically are very painful to touch.

If it is shingles, the sooner she gets the diagnosis confirmed and starts on an antiviral medication, such as acyclovir or valcyclovir, the better. Starting an antiviral early will not cure them but can prevent post-herpetic neuralgia which is a continued, painful problem that can happen even after the lesions go away. It's best to get on an antiviral immediately. The antiviral will also lessen the pain a bit, but the doctor would give a potent pain medication too.

If she goes to an urgent care clinic, she should request to see a doctor as many are staffed by physicians assistants and nurse practitioners who may not have the knowledge to make the diagnosis.

To comment more specifically, I would have to see the lesions with good quality photos, which you can upload here (use "upload reports" button). Close up and a bit farther away - 3 photos, no flash but good lighting.

I hope this information helps.

Hi, I had a dog bite me right below my lower lip and the dogs tooth went all the way through my mouth. The doctor did not suture it, and I clean the outside laceration with hydrogen peroxide and have bacitracin on it. I gargle hydrogen peroxide for the inside laceration. However, I still have numbness around my lower lip and it is swollen. I am unable to smile or frown without pain. Also I can feel a numb with my tounge where the laceration on the inside of my mouth is. Will this ever go away? Thank you and God bless.

Hi, About 3-4 days ago i had a tiny rash in the middle of my back towards the right. At the time it wasn t painful but now it is very sore and starting to feel itchy (although i haven t attempted to itch at all). Now it has spread slightly. Looking at it, it seems to be clusters of small spots some are grey in colour. In addition to this and not sure if this is related but this morning both my underarms have been feeling quite painful (like a bruise ), tender to touch. I bought Lanacane - Anaesthetic cooling cream medication which i started using yesterday afternoon but doesn t feel any different at the moment. Please would you be able to help
