Pain in left side

I had appendicts out 4 months ago. Ever since have pain in left side where one incision was keeps me up at night. When I went back to surgeon for checkup I told him. He told me I could have pain for up to a year. Is this normal

Hi There ..

This is true ..  I was convinced they had left something in !!

For months I had terrible pain especially at night and early morning ..

A year after the op I spent the night in hospital again with pain.

It will go eventually ..
