"How do you feel now?" and "How are you feeling now?" are both questions inquiring about someone's emotional or physical state at the present moment. However, there is a subtle difference in their usage and implications:
"How do you feel now?" This question is in the simple present tense and focuses on the person's current emotional state. It is a more general and straightforward inquiry about how the person is feeling right now, without necessarily specifying any particular emotion. It can be used in various contexts, such as checking on someone's well-being or understanding their emotional state at that particular moment.
"How are you feeling now?" This question is in the present progressive (continuous) tense and emphasizes the ongoing nature of the person's feelings. It is also an inquiry about the person's current emotional or physical state, but it suggests that there might have been some changes or fluctuations in their feelings leading up to the present moment. This form of the question implies that the feelings may have been evolving or that there is a concern about the person's current well-being based on previous information.
In practice, the difference between these two questions might not be overly significant, and many people use them interchangeably. However, the use of the present progressive tense in "How are you feeling now?" might suggest a bit more attentiveness and concern for the person's feelings over time, while "How do you feel now?" can be viewed as a more straightforward and general inquiry about their current emotional state.
