Hello Dr.. I have recently been diagnosed with seborrhic dermatitis. After using the shampoo and creams that my derm prescribed, the dermatitis has subsided and is much less prevalent. However, my lymph nodes are swollen and I have dark red circles under my eyes... I can not seem to get rid of the circles and my throat hurts occasionally due to the swollen lymph nodes in my neck. I thought this was related to the seb derm, however I am now starting to worry. What could this be?
