I was prescribed a potent NSAID...

Am I crazy or are NSAIDs not dangerous for people with IBD? I have Crohns and I went to a doctor for planar fasciitis (basically walked on my feet for WAY too long and now they burn). This doctor knows I have Crohns, as well as RA, but he prescribed me indomethacin which is a potent NSAID (think Aleve, but way stronger).... I probably shouldn't take this right? DISCLAIMER: I am aware yall aren't medical professionals, im just looking for common ground in my worries.
