10 Reasons for Blisters Under Tongue

by Patrick

Almost everyone during their life time will feel blisters under tongue and in most cases this is nothing to worry about. Some however will not heal by themselves and do need to be treated by a doctor. The general rule is to see your doctor if the blisters under tongue cause you any sort of pain or if they have not disappeared by themselves within a few days. Below are 10 of the main reasons for lumps under tongue.

The 10 Main Reasons for Blisters Under Tongue
1. Cold sores – these are also called fever blisters and are caused by an infection relating to the Herpes Simplex virus. These are sometimes accompanied by a fever or swollen lymph nodes.
2. Canker sores – otherwise known as aphthous ulcers these look very similar to cold sores under tongue but are larger in size. Canker sores are believed to be hereditary and usually disappear within one week.
3. Food allergies – this is another common reason for blisters under tongue and is usually accompanied by stomach pain. Again these blisters usually clear up on their own or when the stomach problem is treated. However if the reaction is severe you should speak to your GP immediately.
4. Medication allergies – some blisters under tongue can be caused by an allergic reaction to medication. Stopping or switching the medication usually clears these blisters up within a couple of days.
5. Bacterial infection – Staphylococcus bacteria is another main culprit when it comes to blisters under tongue. The infection generally begins in the gums before spreading to a tongue and medication may be required to clear up the problem.
6. Yeast infection – if the sores under tongue are white it is likely that you are suffering from a yeast infection. This can also cause pain under tongue and you may need some medication from your doctor in order to clear up the infection.
7. Hand, Foot and Mouth Disease – this is one of the main causes of blisters under tongue in young children. If your child is suffering from it you will see red blisters on their tongue and elsewhere in their mouth that are incredibly painful. A rash may also be apparent on the hands and feet. It is always advisable to contact your doctor where blisters on children are concerned.
8. Minor Injuries – sometimes brushing your teeth too hard or eating food that is too hot can cause blisters under tongue. In these cases the blisters will usually heal by themselves within a week.
9. Unclear bowel movements – if you have had trouble passing stools you may notice you have blisters under tongue. A laxative can help with your bowel movements and vitamins can help to prevent the blisters from re-occurring.
10. More serious problems – sometime more serious problems can cause blisters under tongue. In this category are things such as anaemia, leukaemia, syphilis, tuberculosis and Vincent’s disease.

Treatment for Blisters Under Tongue
In many cases blisters under tongue will heal by themselves however if you have any pain under tongue, have had the blisters for a week or more or have any other medical conditions or problems accompanying the blisters it is a good idea to have them checked over by your doctor. The general medication that your doctor will prescribe is a topical ointment containing zinc and anesthetic to lower the pain felt and decrease the size of them. If your blisters are caused by another condition such as a yeast infection your doctor will treat the underlying cause rather than the side effect.

If you find that you get blisters quite a lot it is a good idea to take a vitamin B supplement as a deficiency in vitamin B can often lead to some of the conditions or problems described above. This way you’ll avoid getting blisters or lumps under tongue. Ice, saline water and turmeric are also known to help relieve the pain, treat and prevent blisters under tongue.

On Saturday my daughter who’s almost 4 said her throat hurt. I looked inside with the flashlight and saw small blisters on her tonsils. I took her then to the children’s Urgent Care they checked her for Strep throat and it came back Negative. They finally said it was viral and she had a sligtht ear infection. Monday she wasn’t eating or drinking so took her to her peditrician and he said it was also viral and gave her a script for her ear infection. She’s had hand foot and mouth twice now could she have had this again with the blister under her tongue? She goes to a daycare and this seems to keep going around there. Thanks…Lisa Lee

By the way both Urgent Care nor her pediatric doctor looked under her tongue.
Thanks again,
