I am not good in English literature.
From daily use of English language, it seems to me that the second from in:
1 I am suffering from fever from yesterday
is the correct word. But, my friend, a major in English, is saying that the correct word is since:
- I am suffering from fever since yesterday.
I do not understand why he says that I must use since not from. Can anyone explain which version is right and why?
I am asking for the situation when using the present continuous construction: be + VERBing. I do not mean the present perfect continuous.
I know that in the case of present perfect continuous case we can use since, for, from. However, in a sentence of present continuous structure, then what should we write, from or since? Please explain the grammatical law that forbid me from using from.
