VSL#3 and tenesmus

Hi everyone,

I have ulcerataive proctitis and use canasa 1000mg and a paleo diet to manage. But I know probiotics are recommended and VSL#3 has so much research to support it. 

But I started using it  and found I had an increase in tenesmus and constipation from VSL#3.  I started taking it about a month ago at a low dose (1/32 teaspoon to start 1/4 teaspoon for the past few weeks.)

I had taken VSL#3 years ago and it gave me diarrhea. So I was surprised that it bound me up.  Then the tenesmus started....Not sure why.

Any insights would help!
