felt so painful

[Tan Elaine]

A vampire bit me. I felt so painful that I screamed loudly.

Are the words in bold correctly used? If not, how should I phrase it?

Many thanks.

It felt (was) so painful that I screamed.

The actual bite was painful, not me.
About yourself, you can say;

"I was in such pain that..."
"I was in so much pain that..."

A stronger word than "pain" would be "agony" (used in the same way)

Thanks, Luizao, for your quick clear reply.
