The blisters generally occur near the lips, mouth or on areas close to the face but in rare cases, it can spread to your fingers, nose, neck or inside of the mouth. These small blisters usually appear clumped together in patches or can join to form one big nasty blister. It usually takes a week or two to heal completely. This infection can transfer from one person to another through close contact. The cold sore virus cannot be entirely eliminated from your body and therefore, it may return without warning and lead to severe discomfort.

When you experience cold sores for the first time, it is accompanied with fever, swollen glands, bleeding gums and several painful blisters around the mouth and nose. Usually, people acquire the virus during their childhood and it heals within two to six weeks.

Hello everyone, this is Shreoshi from the cultural capital of India, Kolkata. Well, I have been associated with the content and creative writing for more than a year now after I completed my post-graduation in Journalism and Mass Communication last year (2018). While doing my graduation as an English honour’s student, I fell in love with the subject both literally and metaphorically. As a matter of fact, I recently started teaching a bunch of kids as well, because why not! There’s no harm in spreading a little knowledge right! Writing started as hobby-cum-passion which should become a profession for me. It gives me an immense sense of freedom and helps to channelize my thoughts well. Writing for Anveya has opened up new horizons for me as I realised my articles regarding personal care, home care, and wellness can influence someone’s perception and way of thinking. While a lot of people wanted me to take up political science as my major because I was one of the top scorers in the city, I always believed that creativity and art is where my heart belongs… and it really feels good to know that I was right from the beginning.
