crohn's disease
"I decided to discontinue after the 4th infusion.  Very expensive which might have been worth it had it improved diarrhea.  Instead with each infusion ulcers in my mouth flared worse (they were already there - Crohns in the mouth), severe fatigue, all over body pain, worsened sinus problems, weird tendon-like pain in hands & feet. all of which got worse and lasted longer which each subsequent infusion.  My last infusion's symptoms lasted for weeks!"
