Ibs or ibd. Said nothing abnormal.

I am having constant diarrhea sometimes 2 to 3 times somedays none and also bowel movement is not normal as i feel tightness like blockage but ct scans reveal everything is normal.Recently had a full blood test from thyrocare where the cd8 count was found to be 642 and cd4 count at 390 with cd4 cd8 ratio at 0.61 crp was 2.26 and also protein level were above 8 with both albubin and globulin above higher limit.Again went to my regular doctor who i am going for past 5 years he told lets do a colonoscopy and also before that he gave a blood test which i took which crp was found at 3 and creatinine at 1.1 which was highest till date as previous tests creatinine was never above 0.8.is inflamation i e high cd8 count contributing to elevated crp and creatinine and other stomach disorders i am facing because in colonoscopy doctor said nothing abnormal.Dont know what to do as my symptoms persist inspite of taking librax,rifagut,vsl 3 and amicon.kindly suggest remedy.
