Common Symptoms
A cold sore, also called a fever blister, is a small blister on or near the lips. It is caused by the herpes simplex virus (HSV), most often herpes simplex virus type 1. Abroad, you may not know which treatments are sold in Spain. A cold sore outbreak commonly causes:
- Tingling and itching, or burning, around the lips before a blister appears
- One or more small, painful blisters
- Blisters that burst, then crust or scab over
- Lip soreness or swelling
- Recurrent outbreaks triggered by stress, sun exposure, illness or periods
Cold sores are common and often painful, visible and disruptive. Many people want early treatment to ease symptoms and shorten the outbreak. Most cold sores start to heal within 10 days, but the virus stays in your body and can come back.

How We Treat It
In the online consultation, the doctor checks whether the rash looks like a cold sore (herpes labialis). He asks when it started and whether it is a first or repeat episode. He also checks for eye involvement, severe pain or widespread sores, and asks about eczema, pregnancy and your immune system. Treatment may include:
- Antiviral medication when clinically appropriate, ideally started at the first tingle
- Advice on pain relievers and simple self-care
- Guidance on avoiding spread to others and to other parts of your body
- Advice about sun protection and recurrence triggers
- Referral for in-person care if the diagnosis is uncertain or complications are suspected
Not every lip lesion is a cold sore: a spot, a mouth ulcer or impetigo can look similar. Severe, widespread, atypical, or eye-adjacent lesions may require in-person evaluation.
Clinical Evaluation & Evidence-Based Protocol for Cold Sore Treatment
During a telemedicine consultation with Dr. Pedro Yelamo Vera (licensed medical practitioner No. 484814280 at the Official Medical College of Bizkaia), clinical evaluation adheres strictly to evidence-based medical (EBM) standards. The doctor conducts a thorough history, evaluating symptom duration, aggravating factors, prior treatments, and drug allergies to establish an accurate differential diagnosis.
Private Electronic Prescriptions (Receta Médica) Issued Under Spanish Law
When clinically indicated, Dr. Yelamo issues a private electronic prescription (Receta Médica Electrónica Privada) under Spanish law. The digital prescription contains a secure QR verification code accepted at all 22,000+ registered community pharmacies across Spain for immediate medication dispensing.
Itemized Invoices for Travel & Private Health Insurance Reimbursement
After your consultation, you receive an official medical report and an itemized invoice. The invoice shows Dr. Yelamo's licence details and tax ID. You can send it to your travel or private health insurer (such as Bupa, Allianz, Cigna, AXA or a US travel policy) to claim the cost back.
Preparing for Your Online Medical Consultation
Before your appointment, note when your symptoms started and any medicines you have already tried. Have your allergies and your usual prescriptions to hand. For a skin, rash or eye problem, sit in a well-lit room so the doctor can see it clearly.
Clinical Follow-Up & When In-Person Urgencias Are Necessary
Video care works well for common infections, mild sudden symptoms, skin rashes and repeat prescriptions. Some warning signs need emergency care in person: severe shortness of breath, a high fever you cannot bring down, chest pain or a stiff neck. If you have any of them, call 112 in Spain straight away.
When to Seek Immediate In-Person Care
Seek urgent medical attention if you have:
- Eye pain, red eye, or lesions near the eye
- Severe facial swelling
- Extensive or rapidly spreading lesions
- Painful blisters spreading over eczema (possible eczema herpeticum, a medical emergency)
- Difficulty eating or drinking due to pain
- Significant immune suppression
- High fever or feeling seriously unwell
- A first severe outbreak in a young child or vulnerable adult
- A newborn baby who has sores, a fever or poor feeding after contact with a cold sore
Frequently asked questions
What is the treatment for a severe cold sore?
Severe cold sore treatment may include antiviral tablets such as aciclovir or valaciclovir, after a doctor's assessment. They work best when started early, ideally at the first tingle. Seek urgent care if your immune system is weakened, the sores spread widely, or a sore appears on or near the eye.
Can cold sores be treated online in Spain?
Yes, many uncomplicated cold sores can be assessed online. Antiviral treatment may be considered when started early and when clinically appropriate.
Do I need antiviral medication every time I get a cold sore?
Not always. Mild episodes often heal without prescription treatment. Antiviral creams may not work once blisters have appeared. A doctor may suggest tablets if your cold sores are very large, painful or keep coming back.
What home remedies help a cold sore?
Pain relievers such as paracetamol or ibuprofen can ease pain and swelling. Do not give aspirin to children under 16. Avoid acidic or salty food if it stings, and use a lip balm with SPF 15 or higher outdoors. There is little evidence that light or laser devices work.
Is a cold sore contagious?
Yes, from the first tingle until it has fully healed. The virus spreads through skin-to-skin contact, such as kissing, and through saliva, especially while blisters are present. Avoid kissing and sharing lip products during an active outbreak. Never kiss a baby while you have a cold sore: neonatal herpes is rare but very dangerous.
Can I have oral sex if I have a cold sore?
No. Avoid oral sex until the cold sore has completely healed. The virus can spread to your partner's genitals and cause genital herpes.
How do I stop a cold sore spreading to another part of my body?
Do not touch the sore, except to dab on cream, and wash your hands each time you do. Keep your hands away from your eyes, as the same virus can infect the eye.
Who should see a doctor about a cold sore?
See a doctor if the sore has not started to heal within 10 days or is very large or painful. Also see one if you are pregnant, have a weakened immune system or get cold sores very often.
What can a pharmacy in Spain offer for a cold sore?
A pharmacist can advise on creams and on cold sore patches, which cover the sore while it heals. Creams work best when you start them at the first tingle. Follow the leaflet. Ask a doctor first if you are pregnant, if the sore is near your eye, or if it is your first outbreak.
