"I feel well" and "I feel good" these both sentences are used occasionally, but what is difference between them. I mean when someone ask to a patient "How are you feeling now" and he replies "I feel well" or "I feel good" then the person who is asking this question might be confused. I mean in which context patient is informing. Thanks...

You know that after "feel" we need to use adjectives, not adverbs, don't you? For example, I feel ill, cheerful, bad, etc.
So, if well is an adjective, then it means healthy: I feel well = My health is good.
And if you feel good, then you feel happy ("I feel good! And I feel nice, like sugar and spice!" - from James Brown's "I feel good").
However, good can also mean healthy depending on the context:
I don't feel very good. I need to lie down.
In this case good and well are interchangeable.
2Some prescriptivists would argue that "I feel good" would mean that the speaker does not feel evil at the moment. Nov 9, 2018 at 12:58
1As a Briton, when I say "How are you?" to an American, and he/she says "I'm good", I want to say "I wasn't enquiring about your moral status". Nov 9, 2018 at 14:13
I should perhaps modify my comment to read "to an American, or a British millennial". Nov 9, 2018 at 21:10
