Hi. My Husband Was In The Hospital 4 Mild Pneumonia

Hi. My husband was in the hospital 4 mild pneumonia and folliculitis on his head. He was given IV antibiotics and is continuing to take two different types of antibiotics at home.
He was released on Sunday and has not felt well since. Today he's developed some numbness from his left side of his face to his right. He says that his left eye is a little droopy. In light of all that has happened this week don't you think he should go to the ER? Thank you Kathy
