It sounds like you're experiencing some concerning symptoms with blisters in your mouth, particularly following a meal. Based on your description, the blisters might be related to a few potential causes, such as an allergic reaction, irritation from certain foods, or even a viral infection, especially considering your history with cold sores.

Explanation:

Blisters in the mouth can occur for various reasons:

• Food Allergies: Given your history with Oral Allergy Syndrome (OAS), it’s possible that the tortilla or a specific ingredient caused localized inflammation and blisters.
• Herpes Simplex Virus: The cold sores you mentioned suggest you might be prone to herpes simplex outbreaks, which can occasionally affect the mouth and lead to blistering.
• Irritation or Trauma: Sometimes, sharp food items can irritate the delicate tissue in the mouth or provoke blisters.
• Gastroesophageal Reflux Disease (GERD): This condition can also cause irritation in the throat and mouth, potentially contributing to blister formation.

Next Steps:

Here are some prioritized actions you can take to manage your symptoms:

1. Rinse with Salt Water: Mix half a teaspoon of salt in a glass of warm water and use it for a mouth rinse. This can help soothe irritation and promote healing.

2. Monitor Your Diet: Keep a food diary to record any foods that may trigger blister formation or worsen your symptoms, particularly focusing on items associated with your OAS or common allergens.

3. Avoid Irritating Foods: Steer clear of spicy, acidic, or rough-textured foods until the blisters heal. Soft, bland foods may be easier on your mouth.

4. Use Over-the-Counter Treatments: Consider topical treatments for cold sores (like docosanol) that may also ease symptoms in the mouth. Ensure they are safe based on your current medications.

5. Keep Hydrated: Drink plenty of fluids to help soothe your mouth and prevent dehydration, especially if you're avoiding certain foods.

6. Observe Symptoms: Note any changes, such as increased pain, swelling, or if new blisters appear elsewhere. This information will be helpful if you need to seek further evaluation later.

If symptoms persist or worsen, such as the presence of fever or significant discomfort, I encourage you to follow up with a healthcare provider for a more thorough assessment. I hope this helps, and I'm here if you have any further questions!
