can probiotics make you worse

If you get a bad reaction from anything then please stop taking it, especially if it is a supplement not prescribed by a doctor. I take probiotics but some are incompatible for me. VSL#3 and Culturelle at one time worked wonders but now are ineffective or worse. I think it might be because they have since added some extra ingredients and other junk into the formula.

That being said you might be experiencing the "Jarisch-Herxheimer reaction" or Herx which is a temporary healing crisis. It typically happens when large quantities of toxins are released into the body as your bad bacteria die off and are replaced by the good bacteria from the probiotic. It can occur during antibiotic treatment or too rapid detoxification, and lasts about a week.

I've never been able to afford probiotics >.> (At least not a decent one.)

The evidence for probiotics as a treatment for Crohn's is very limited/poor though. And while they can help with some people's symptoms, they can also make some people's symptoms worse. Personally I'd save your money and look for other things which might relieve symptoms (be wary of cranks online offering 'miracle' supplements though). Also, there is a difference between relieving symptoms and treating inflammation: diets, imodium, etc. can relieve symptoms, but leave the underlying inflammation intact. It is important to try and treat the inflammation as well, because left untouched it can cause permanent damage to the intestines. (Depends largely on how bad it is.)

Sorry if you already knew all that - I got a bit carried away.

I can't tolerate probiotics. I tried several brands, too. But everytime I took them they exacerbated my diarrhea so I forgot all together about the idea of taking probiotics.
