Hello. I got bit by fire ants Tuesday morning, and it has developed in to a fairly large blister. I was wondering if I should pop it or not.

Allergic response: This sounds like either a localised allergic response to the bites or development of an abscess. In any case you need to get this examined by a doctor. If there is an abscess they will need to incise and drain it. If its a simple blister it is best drained under sterile conditions or it may get infected. Antihistamines may reduce the reaction. The blister is best kept covered. ...Read more

Is it okay to pop a large blister that has formed after a wart was frozen off? I am diabetic.

Is it okay to pop a large blister that has formed after a wart was frozen off? I am diabetic.

Don't pop blisters: Blisters are fluid-filled collections under the skin. More importantly, they're sterile until they're popped. So leave them alone so that the new skin underneath can stay sterile and minimize risk of infection. Forming a blister after cryotherapy is normal - just leave it alone and let your body absorb the fluid. Keep it covered to minimize risk of rupturing it. Look out for redness, pain & pus. ...Read more

Gum boil: It is high time for you child to see a dentist. The gum boil may signal a dead baby tooth, or even one of the adult teeth. Either way, they need immediate treatment. If a baby tooth is dying or dead, and abscessed, then the developing tooth underneath it can be affected. Abscesses and infection can spread to the neck, brain, and become serious--all quite unexpectedly, with devastating results. ...Read more
