Hi.... Welcome to healthcare magic.. According to your complain you have problem of swollen lymphnode that may be because of any infection condition. Dental cause or ear infection problems cause swollen lymphnode. Impacted third molar lead to infection surrounding areas. Vitamin deficincey also ruled out. Dandruff in hair can cause lymphnode swelling. Acne on face area also cause swelling of lymph nodes. Detail history and physical examination give exact idea. After palpation of lymph nodes give exact information. Consistency and tendernes helpful for diagnosis. Consult a physician for further diagnosis. I hope my guidance helpful to you.. Take care. Thank you. Dr Rachana R Goswami.
