Perhaps you should try some spelling variations:
decrease buffer » decrease after (Expand search), decrease burden (Expand search), decrease suffering (Expand search)
buffer objects » buffer effects (Expand search)
decrease pain » decreases pain (Expand search), decrease in (Expand search), decreased brain (Expand search)
pain decrease » can decrease (Expand search), strain decrease (Expand search), taping decrease (Expand search)
decrease to » decreased to (Expand search), decrease toc (Expand search), decrease the (Expand search)

You may be able to get more results by adjusting your search query.

• Removing quotes may allow a broader search: (( decrease pain decrease to decrease ) OR ( decrease NOT decrease buffer objects ))~.
