Tonsil blister: Hello. It is hard to determine why your tonsil is irregular without examining you. It may represent a crevice or crater on the surface of your tonsil that could be totally normal. Another possibility could be a benign mucus cyst which also could be normal. See your ENT for confirmation. Good luck. ...Read more

I have a blister on my tonsils for a month now. Was just diagnosed w/ strept throat. Is this a symptom of strept?

Could be.: If it goes away with the treatment for strep, then you have your answer. If it does not, get another culture to see if strep is still present, although it may be if you are a carrier. In either case, if the antibiotics don't help, see an ENT doc, any new lesion still present after a 4-6 weeks needs to be evaluated. ...Read more

I have tonsillar hypertrophy. For the past 24hr Ive had an sore throat, no appetite & a what looks to be a blood blister on my tonsil. What is this??

Tonsil lesion: It could be a small blood blister, could be a dilated blood vessel on the tonsil, called a varicocele, which is a normal variant. Sometimes you notice things that have been there because your attention is drawn there, in your case due to sore throat. Doesn't sound concerning to me, but you should see an ENT doctor to check it out. ...Read more

Viral vs bacterial: This could be many things. Strep throat causes fever headache and sore throat often with what is called exudate. Mono can have similar symptoms as well. Viral illnesses usually cause blisters that are whitish centrally with surrounding erythema, ie redness. Very important to make sure your child is able to drink well and swallow, if not your child should be seen asap. ...Read more

Sore throat, red blisters, and swollen tonsils for 3 weeks. On 4th day of amoxicillin but there's been no improvement. What do I do now?

Sore throat, red blisters, and swollen tonsils for 3 weeks. On 4th day of amoxicillin but there's been no improvement. What do I do now?

Virus? Mono?: Most sore throats and tonsillitis are caused by viruses -- and no virus is cured with any antibiotic. Your doctor probably was concerned about strep throat, but that should have started to improve by now. At age 20, a good bet for such prolonged viral pharyngitis is infectious mononucleosis. Ask your doctor if s/he checked for mono or if you should be tested now. ...Read more

I have 3 dark purple spots that look like blood blisters  on my lingual tonsils, should I worry this is cancer? Have had a sore throat for 3 weeks.

No: The tonsils are subject to a great deal of inflammation under certaincirdcumstances. Where there are the occassional cases of malignancy developing it is either from squamous malignancy or lymphoma. Neither present as hemmorhagic areas. The latter can occur when there is some bleeding into the tonsil because of proximity to the underlying intermal caroltid artery. Warm gargles should help. ...Read more

I have a swollen uvula with a white looking spot or blister, I have my tonsils removed n have a sore throat and a gagging feeling in my throat help?
