Hello, Lymphnode swelling is usually secondary to infections elsewhere. I do not understand what you mean by pollen - ruptured lymphnode (abscess) with yellow discharge or flower pollen. If it is the first - consult your doctor at the earliest. If you are worried about the second one, get a blood count done, specifically for eosinophils. If its increased, possible allergic cause can be attributed. In developing countries commonly cause of a enlarged multiple cervical lymph node is Tuberculosis. Do continue the treatment until it disappears, otherwise further investigations are necessary to identify the cause. Hope i Have answered your query. If you have any further questions, I will be happy to help
