I have a pain in my stomach.
I have pain in my stomach.
Can anyone please tell me how these two sentences differ in meaning?
I'm quite confused.
As Raymott said, both the OP's sentences are perfectly acceptable, though their meanings are subtly different.
Differentiating two pains in the actual stomach might be difficult, but it's possible.
It would be very handy though not to be able to have two pains at once.
If you could only have one pain at a time, and you came to see me with a fractured leg, I could make that pain disappear immediately by hitting your thumb with a hammer.
Its just that I have not heard such a sentence construction out here in India. An indian speaker will perhaps prefer the other statements which I had posted out there in my first reply.
