Perhaps you should try some spelling variations:
decrease lesions » disease lesions (Expand search), decreased response (Expand search), decrease adhesion (Expand search)
decrease working » decrease walking (Expand search), disease working (Expand search), decrease during (Expand search)
lesions decrease » response decrease (Expand search), lesions case (Expand search)
working process » making process (Expand search), work process (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)

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease pain decrease working process ) OR ( decrease AND decrease lesions decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease pain decrease working process ) OR ( decrease AND decrease lesions decrease ))*.
