Hi and thanks for the query, i am afraid Helicobacter pylori infection might have nothing to do with the swollen tongue and the red throat. It is important to carefully to examine the tongue and throat in order to identify the possible causes of these symptoms. helicobacter pylori has effects mainly in the stomach where it contributes to peptic ulcer disease. Redness in the throat could be caused by an inflammation, either due to virus and bacteria generally. Depending on other associated symptoms, it would be easy for your physician to know whether it is of bacterial or viral origin. High fevers, lymph node swelling and white patches are generally seen in bacterial infections. Treatment depends on the cause. I suggest you consult your primary care physician. Diagnosis and management in this case should not be complicated. Best regards, Bain LE, MD.
