Personally with due regard and respect of the opinions of others, I really do not think that the possibility of a connection between Crohn's and osteoarthritis can dismissed out of hand.Putting aside the medications that are specifically designed to treat both Rheumatoid and Psoriatic arthritis, many of us have been prescribed Methotrexate and Salazopyrine which are are used in the treatment of these two types of arthritis and our own beloved Crohn's!
Crohn's is after all an autoimmune ailment and I don't think that it is unreasonable to consider the premise of a possible comorbidity. Nevertheless, Chuckmya I think that I would go down the corticosteroid injection track. I do, or have transient bursitis on my right hip which responded to this type of treatment for a shortish period, however since i started of Stelara almost a year ago this has oddly ceased. Coincidence, I dunno. Mind you once you get past three score years and ten anything can and does fall off!
