Suggest Treatment For Chronic Diarrhea

I have had diarrhea since last Tues evening First BM was totally normal but then runny loose bowels set in I have had diarrhea since then first day I went 15 times then 10 etc today I would say it was 8 Stool is very small now a bit bigger than fishworms I get an ugly feeling in lower intestine and then I know I have to have a bm Years ago I had something similar and eventually it let up with watching diet BUT also years back due to an antibiotic I had c diff I was in hospital for gall bladder in Nov I am sure I would be affected by now The only thing I ate different that evening was chicken sausage My family also ate it and had no ill effect I am wondering if I should give it some time, eat yogurt and see what happens or what?
