Could Bloating And Inflation Of Intestine Be The Symptoms Of IBS?

hi doc,
I was diagnosed in 2012 with IBS However, I have been doing great and no stomach pains until a week ago. My stomach is bloated at the top ,feels as if my intestines are inflated. its uncomfortable to wear a bra. Also, two weeks ago i finished a 28 day cleansing. and I notice when that was over stomach issues began. I am also taking probiotic (sorry about the spelling error. I also in 2011 had a small part of my colon remove. I had a noddle enlarged in my appendiics. It wasn't cancerous. My fear is that I might have cancer. I have scheduled an appointment with my GI doc. but he can't see me until February 6. Shall I continue taking a tylenol until I see the GI for pain? Please advise.
Worry Mrs. Annie
