Feeling well but woke up with very painful lumps behind each ear...Now my front lymph glands are also up. But no sore throat. Not sure of cause?

Lymph node. Enlargement in those areas are usually benign esp if they are small and not accompanied by other symptoms.They could be from a viral, bacterial, respiratory or surrounding skin infection. See your dr for an accurate diagnosis. Take care!
Swollen lymph nodes. A viral disease is the most likely explanation and you don't have to have sore throat because different viruses work differently.
