Same thing with my swelling ankles.
My GP said I must have twisted my ankle or hit it on something...Uh NO I DIDN'T, I said,
In January, my GI told me my swelling ankles were NOT related to Crohn's...until I said, "But don't you think it could be Crohn's Arthritis?" and then he said, "Well it could be, but not likely."
2 months later I went to my GI's office to see his Nurse Practitioner. He IMMEDIATELY said, "Oh yeah - you're definitely in a flare. Those swollen ankles say it all!"
The NP ended up telling me that they had a college student as a patient who had to skip a semester of school because his ankles were swollen so bad he couldn't walk for months. He's been diagnosed with Crohn's yet has NO intestinal problems whatsoever. His Crohn's shows up in the EXTRA-intestinal stuff...like swollen feet....
