Joint Pain STILL

Hi All - So I have posted on this a while back, but I am STILL having significant joint pain, especially in my knees. I saw an arthritis doctor who just chalked it up to my Crohn's and told me to take Tylenol daily and 5mg Prednisone on really bad days. This has been present since my surgery in September. I feel so sore in the morning and getting up from laying down or sitting. I work with preschoolers and am on the floor at least half of the day and always dread getting up or manipulating my position much. Do you think I should contact my GI about increasing my Cimzia (I am currently taking it 1/month)? I don't know what else to do but this is really starting to impact my day-to-day and getting annoying.
