Hello, Your description indicates the bumps are located outside your mouth on your cheek along the jawline. I do not think this would be from your mouth unless your saliva has irritated your skin. Viruses can be carried in your saliva. A heat rash is most likely with your medical history and description. Your sweat glands contribute to the condition. Keep your face clean and avoid hot and humid conditions. Keep HY Chat Doctor.  Contact dermatitis or an allergic reaction is possible. If you are referring to inside your mouth, I expect this to be from an irritant. Considerations are
