I am having a fever. I have a fever. I may be coming down with a fever. - Which one is correct?

Someone with a fever is when his body temperature is reading above 98.6 degrees F. You can say then " He has a fever", or he is having a fever. If you are not sure but his forehead feels hot to the touch and you don't have a thermometer, you can say " He may be coming down with a fever".

It isn't incorrect grammatically. In fact, it's perfectly grammatical. It just isn't used. Many verbs are not used in the continuous tenses at all. Have can be used in continuous tenses in some cases, but not in all of them. You can say: I'm having

The verb "have" is sometimes used actively, and sometimes statively.
If it means "to own" or possess then it is stative. The progressive is incorrect.
If it means present, throw, or some other active activity, then it is active. The progressive is correct.

Are you from some part of the world in or near India, or living in an Indian community elsewhere? There people commonly say "I am having" when the correct form is "I have". If you live there and you hear it that way all the ti
