Mouth problems

What could be making my tongue and the inside of my mouth swell and feel very rough when my tongue touches my jaw or the roof of my mouth?  My inside jaws also have a darkness about them.  I'm afraid that my tongue will constrict my airway.

Hello Dear,
Your condition seems like stomatitis.
Inflammation of the mucous lining of any of the structures in the mouth, which may involve the cheeks, gums, tongue, lips, and roof or floor of the mouth. The word "stomatitis" literally means inflammation of the mouth. The inflammation can be caused by conditions in the mouth itself, such as poor oral hygiene, poorly fitted dentures, or from mouth burns from hot food or drinks, or by conditions that affect the entire body, such as medications, allergic reactions, or infections.
Stomatitis is an inflammation of the lining of any of the soft-tissue structures of the mouth. Stomatitis is usually a painful condition, associated with redness, swelling, and occasional bleeding from the affected area. Bad breath may also accompany the condition
Poorly fitted oral appliances, cheek biting, or jagged teeth can persistently irritate the oral structures. Chronic mouth breathing due to plugged nasal airways can cause dryness of the mouth tissues, which in turn leads to irritation. Drinking beverages that are too hot can burn the mouth, leading to irritation and pain. Diseases, such as herpetic infections (the common cold sore), gonorrhea, measles, leukemia, AIDS, and lack of vitamin C can present with oral signs. Other systemic diseases associated with stomatitis include inflammatory bowel disease and Behçet's syndrome, an inflammatory multisystem disorder of unknown cause.You should consult a physician  and treat the disorder.
