Abdominal pain and loose stool after using probiotics

Hi,

I discontinued use of 100mg of Acidophilus about 3-4 weeks ago because of loose stool and abdominal pain. However, I still have it. I'm going 3-4 times a day mostly in the morning. If it helps to understand I do have GERD but it is well managed on 20mg Protonix that I've been on for years. I haven't changed anything in my diet which I'll be honest isn't the greatest. I know diet could help but beside that, is this normal? It almost seems like something in my gut has permanently changed and not for the better. Should I see a doctor or is there something I can do from home?

Thanks!

I would see a doctor.  The symptoms sound like IBS.  Does yiur pain move about or stay in one place?

I think it does move higher or lower in my stomach at times. Is it common for someone to not have IBS one day then have it another? Because the change was night and day when I started taking the probiotics.

IBS often comes and goes in flare ups caused by either diet or stress. My IBS started with constant symptoms for three and a half months virtually over night and now it is in remission.
