I have a tight feeling palatoglossal arch a little scaly in texture, and a small bump at the top where it connects behind the top molars, maybe a swollen gland. i also have a single swollen lymph node. all began about 3 weeks ago, feel otherwise fine?

Watch and wait: You may feel the node every couple of weeks, if the lymph gland doubles in size, becomes painful, ulcerates, or other nodes become enlarged, or you develop fever, or lose weight, you should see a doctor. Wish you good health!

Oral lesions: Rule of thumb is that all oral lesions that demonstrate pain &/or bleeding &/or swelling should completely disappear in 2 weeks from onset. If not, evaluation is strongly recommended. See your General Dentist, a specialist Oral Surgeon, your General Physician, or an ENT specialist
