JT says, "living with this can be relentlessly debilitating, both mentally and physically" ... and, he says the diagnosis clarified so much of the pain he felt while performing.

Despite the pain, Timberlake said he couldn't dream of giving up performing ... explaining that he "decided the joy that performing brings me far outweighs the fleeting stress my body was feeling. I’m so glad I kept going."
