The Prometheus Blood diagnostic test is as reliable as your psychic’s Crystal Ball. I had that test read by the top pathologists on the east and west coasts and was inconclusive as well as CT and MRI Enterographies which were also inconclusive. Be leery of chasing a diagnosis, lots of money in it for radiologists and pathologists who get referrals from their buddies, but these tests are notoriously unreliable and Prometheus is quasi-scientific. Best thing to do is focus on treatment. The blockage could be due to residual swelling (you haven’t given us a timeline) or scar tissue. I had numerous blockages while still swelled after takedown. Careful diet is probably a good idea.
