Patient's Query

Hello doctor,

I have been under a considerable amount of stress. I have been biting my lip a lot lately. However, I notice more and more odd things occurring in my mouth. Unsure if normal or is a cause for suspicion. There is a red bump on the hard palate on the grooved surface, mildly irritating or with pain. The lesion is in the corner of the mouth and is a red dot. It is mildly bothersome. Achy front teeth- gum flap in between teeth. Mild to moderate pain lesion is there in cheek and there has been receding gum for a while. It is annoying with no pain or irritation.

Welcome to icliniq.com.

Such multiple lesions usually can occur either in vitamin deficiency or even herpes simplex and a few other conditions. In your case, it appears that you need Multivitamin capsules. Take a Multivitamin capsule with Vitamin B complex once daily for 15 days. Since how many days, have you started seeing these lesions? Use warm salt water gargle twice a day for a week or two. Start taking a balanced diet with a lot of veggies and some meat and egg products. Avoid snacks and spicy food too. Can you explain your typical weekly diet?

Patient's Query

Thank you doctor,

Lately, my diet has been poor over the course of four weeks. I have not been drinking much water or eating much of anything. I have been very anxious and stressed. I consume a moderate amount of sugar. What would cause a sore in the corner of the mouth on top of gum? It does not seem like a canker sore.

Yes, then I believe your stress and less water can be the main cause of the multiple sores. Start taking a lot of water and a good balanced diet with more meat products too. A multivitamin capsule is good for 15 days. Anxiousness and stress should be reduced as well and try to relax.

Same symptoms don't mean you have the same problem. Consult a doctor now!
