I am fairly new to this, and I haven't had this symptom but it doesn't sound normal to me. Hopefully someone will come along with more information that will help you. Hope you get feeling better soon.
Living with Crohns for 1 year. I have a wonderful husband and two beautiful little girls.
One blessing that came with my Crohns: I thank God for each day that I can get out of bed and take care of my girls and my home.
