Is there any way to get reasonable pain relief with severe Crohn's disease?

[Crohnically_Serious]

I have very severe pain on a relatively frequent basis, about 2 episodes a month.  I am on humira and it seems to be helping all the other symptoms but the pain.  My gi doc only ever offers antispasmodic meds.  The pain I am feel IS NOT cramping...believe me I know what cramping is.  Not sure what to do.  Any advice would be appreciated.  Before you ask I know it's not an obsruction...everything is working fine in that department since they increased my humira dosage about 2 and a half months ago.
