Can flu cause a flare?

[CeeCeeGo]

Had proper flu & pleurisy just before Xmas. 3 weeks before getting flu had loading dose of Ustekinumab. Had first 8 week injection of Ustekinumab. Two weeks after first *** starting to flare and FCP test went from 93 at 8 weeks to 300 at 12 weeks. Consultant decided to give an additional injection at 12 weeks but still flaring. Next injection due at 16 weeks and then we decide if it is working.

I am wondering if my immune response to fighting off the flu and pleurisy triggered a flare? Interested to hear people’s thoughts.

I am not sure if fighting off the flu and pleurissy would cause a flare. In 1991, around Thanksgiving, I had the flu. It threw me into a flare.
