A common side effect of steroids is swollen feet and ankles. I had this when I was on prednisone, to the point that I had trouble putting on my shoes. Since Entocort is a steroid, I wouldn't be surprised if that's what's causing your symptoms, and the fact that you're not peeing much suggests water retention, which goes hand in hand with the swollen joints. Side effects like this sometimes improve over time, but not always. Anyway, as with any new side effect that pops up, it's worth putting a call in to your doctor. You may need a dosage schedule adjustment, or sometimes another med can be prescribed to offset the unpleasant symptoms.

I have been taking 9 mg Entocort daily for the last 3 months, together with the usual battery of antibiotics, and I have experienced no side effects, and also no noticeable difference in my condition, as I deteriorated when I went off antibiotics but with a slightly longer onset of the deterioration (9 days rather than 5-6). I am trying to posture for a rotation of antibiotics one week and none the next, while on Entocort.

I took Prednisone for nearly 20 years and I had side effects with it but none with Entocort, so far.
