I'm Having Yellow Fluffy Looking Stool And I Have Abdominal

I'm having yellow fluffy looking stool and I have abdominal cramps that sometimes double me over. I also have pain on the left side of my abdomen just underwhere my ribs end., I also get this strange flutter feeling that feels deep not like it's in my muscle but my organ it doesn't hurt it's just strange. I've been doing this since I had a full hysterectomy in 2013. My doctor doesn't seem to know and I was told to go back to the doctor that did my hysterectomy but she's no longer practicin. Any ideas?
