I may have solved my own mystery.............I rarely get fever blisters but have changed my diet to Keto due to my husband being diagnosed with Parkinsons. One of the things I started doing was getting high fat yogurt, cream, buttermilk and keifer from a nearby dairy. The past month I have been constantly plagued with fever blisters at the corners of my mouth and nostrils.
Certain Foods
Consuming arginine-rich foods – such as beans, meat, chocolate and dairy – can trigger or worsen a cold sore. This is because arginine is required for the virus to replicate. Acidic foods and beverages can also trigger a cold sore outbreak. This includes citrus fruits, tomatoes, orange juice and even soda.

An imbalanced ratio of arginine: lysine will cause Herpes Simplex/Cold Sore/Fever Blister breakouts. Try to eat your arginine foods as little as possible... And stop them altogether as soon as you feel the tingling.
