Hi, I'm not sure I've quite understood from your post which doctors you are seeing - were you diagnosed with Crohn's by the colonoscopy? A rheumatologist wouldn't normally be the one in charge of managing Crohn's, so I wouldn't be too disheartened if he didn't help with it, it's the gastroenterologist's area of expertise. Sometimes Crohn's can cause damage over the long-term even without causing digestive symptoms, which is why your doctors feel you need medication even if you don't feel unwell from it. But at the same time, if you've had a recent colonoscopy and no significant symptoms, they may feel a lot of invasive testing is unnecessary. They may want to wait and do more testing after the medication's had a chance to kick in, to see how well it's working. Do they think the leg pains and swelling are to do with the Crohn's?
Sorry if I've misunderstood your posts - do you have any specific questions?
