What Causes Swelling And Blisters On Lips?

I ve had this small blister on my lip and as the days progress, more little red bumps on my lip appeared and that caused my lips to swell..this had gone on for 6 days i believe then the swelling went down and the blisters were hardly even noticeable. Two days later, i woke up and my lips began to swell again, appearing very dry and chapped and little red bumps appeared again. I believe it was something i ate that gave me this reaction but i cant seem to find out what it was that i ate. Please help. it is very embarrassing to go out with my lips like this.

Hello,

I can understand your concern. You are right in your assumption that you have developed an allergic reaction to some substance that you are not aware about.

You should start taking antihistamine such as Levocetrizine 5 mg (Levocet) or Loratidine 10 mg (Lorfast) once a day for about 5-7 days. This will reduce the swelling and will make the red bumps disappear.

After about 10 days to 2 weeks' time, go for a blood test for allergy. This test will show what substance you are allergic to so that you can avoid exposure to it in future.

If the antihistamines do not help, then it is not an allergic reaction and you should see either a dermatologist or a dentist for examination of your lips and further investigations to diagnose and treat the condition.

I hope this information helps you.Thank you for choosing HealthcareMagic. I wish you feel better soon.

Best,
Dr. Viraj Shah
