Many times when you get blisters like this on your tongue, they are referred to as Fever Blisters. These are not canker sores, but instead they are derived from a virus, the herpes simplex virus. They are common on the tongue, and develop like you are mentioning. Most people contract this virus as a child, and as they grow older, it can be reactivated b/c it stays within your system. It cannot be eliminated. The virus only gets reactivated by certain factors such as allergies, sun exposure, stress, respiratory illnesses, menstruation, and trauma to the skin.
The herpes simplex virus cannot be eliminated, there are several treatments available.
1. Use zinc cream on the blisters to promote healing.
2. Keep the blisters clean and dry in order to minimize the risk of further infection
b/c if they break, they can spread.
3. Eat soft food that can be easily swallowed. Avoid eating or drinking acidic food and drinks that would irritate the blisters and sores and aggravate them b/c this could lead to spreading as well.
4. Don't kiss others b/c it can be spread this way too.
5. Try to reduce the stress in your life b/c some have said that this can cause them to be reactivated and form.
6. Avoid chocolates, nuts, seeds, and grains. Instead, eat more dairy products, legumes, fish, meat, and wheat germ.
I hope you recover soon. Remember that this is a self-limiting virus and it resolve on it's own in a matter of 1-2 weeks.
