Hi , 17yrs ago I was admitted to hospital with a small bowel blockage , the blockage cleared itself within a few days and I was discharged. They carried out follow up colonoscopy and ct scan and found some tiny ulcers in my ilium . Stated I possibly had crohns and put me on Pentasa , was on pentasa for a year had no symptoms and was taken off it and discharged. Prior to the obstruction I had a back disc issue and had been self medicating with ibuprofen for months at a high dose so at the time of the obstruction I put the bowel issues down to the ibuprofen. Have had no bowel issues since ( 17 yrs ) but a few months ago took around 12 ibuprofen over 4 days , few weeks later started with bowel issues, bloods all clear but cal protectin came back at 83 , have carried out a second test this week and it’s now 284 which points to ibd . Got app with gastro but just wondering is it possible for crohns to lay dormant for 17 yrs ? And for me to have an adverse reaction to ibuprofen which has caused this flare up ? Symptoms at present are stomach ache , bloating , bowel moment once a day on a morning ( what I would call a fluffy stool ) also a calprotecin level of 284 , what are the usual levels associated with crohns
