I took a Word to Work with Me #2

This is probably a stretch but was it

And it made me feel quite retentive

Rearranging it was quite an incentive

And damaged my lymph node

Is the word...

I took a word to work with me
And it made me feel quite retentive,

Then when lunch came, my friends would agree,
Rearranging it was quite an incentive

Come home time and I reversed direction,
To get me to my abode,

But my ire was combined
As I was hit from behind
And damaged my lymph node
