how to heal sore in corner of mouth - #25996

Rohan

I am dealing with this really annoying sore in the corner of my mouth. It started a few days ago, and I thought it was just a small cut, but it got worse. Now, it’s kinda swollen and feels super tender. I’ve tried applying some lip balm thinking it might help, but clearly, that didn’t work. I remember I had a similar sore in the corner of my mouth last year, and it took forever to heal. I really don’t wanna go through that again! I also noticed that I’ve been a bit stressed lately, like with work and stuff, and I wonder if that has anything to do with it? Should I be worried about this sore in the corner of my mouth? I keep looking in the mirror to check it, and I can’t help but think that it might turn into something worse if I don’t do anything. I’ve read some folks say it's just a canker sore or maybe it could be related to nutritional deficiencies? I don’t even know. Anyway, does anyone have any tips, or know how to heal sore in corner of mouth quickly? Or should I be thinking about seeing a doctor if it doesn’t get better soon? Would love any advice!

The sore in the corner of your mouth sounds like it could be angular cheilitis, which is common and usually caused by a combination of factors like saliva accumulation, fungal or bacterial growth, and sometimes nutritional deficiencies. Stress might exacerbate the situation by potentially lowering your immune system’s effectiveness but is not the direct cause. You’re not alone in experiencing this, and fortunately, there are ways to promote healing. First, ensure the area is kept dry as moisture can worsen the condition. You can use a protective barrier like a simple, unscented emollient ointment—such as petroleum jelly, which helps shield the area. Avoid licking your lips or touching the sore with your hands, and if possible, address any habits like lip-biting that might irritate it further. Over-the-counter antifungal creams with clotrimazole or miconazole might be beneficial should a fungal infection be suspected. In terms of nutrition, making sure you’re getting sufficient iron and B vitamins (such as B2, B3, B6, B12) through your diet can be crucial, although taking a supplement blindly isn’t recommended without knowing your specific needs or deficiencies. If the sore doesn’t show signs of improvement in a few days or becomes more painful, it would be wise to seek medical attention. A healthcare provider can provide a more definitive diagnosis and may prescribe stronger topical treatments or address any underlying issues contributing to the problem. Taking a multivitamin could also be beneficial but consult your doctor first, especially if you suspect a deficiency. Lastly, stay hydrated and aim for a balanced diet as a preventive strategy in the future.
