Conditions that can afflict the submandibular lymph nodes include mouth infection, oral cancer, lymphadenopathy, swollen lymph nodes, metastasis of cancer, leukemia, and lymphoma.
Here are some simple steps you could take to shorten UTI: 1  Avoid foods and drinks rich in sugar. 2  Other foods to avoid are processed foods, spicy foods, fats, dairy products, red meats and shellfish. 3  Take a high quality probiotics that will help combat the infection more effectively.
Even when I wasn't having a UTI, I had irritation and burning in my bladder that got worse with any spicy food, onions, tomatoes, carbonated drinks, alcohol, or caffeine (although the specific irritant foods may be different for different people). Try to avoid foods that irritate you so your bladder can heal faster.
