I've been taking cymbalta (duloxetine) for my fibramyalga for 2 years i've noticed an increase of pain does a body get amuned to this cymbalta (duloxetine) ?

No.: Your body does not become immune to any medication. Sometimes for unknown reasons people with fibromyalgia lose their responsiveness to a specific medication and benefit from a switch in therapy.
