Pain in abdomen, high crp level.

Facing pain in abdomen and lower back that shifts from lower abdomen to upper abdomen, sometimes on sides from last 1 month. Also I feel urge to pee every hour or so and face burning sensation as well in urine. Ultrasound, Urine reports are normal. Blood test report states higher CRP level exceeding 10 and eosinophils is also high(please check blood report attached) and abdominal X-ray shows some waste in intestine. Gastroenterologist suggest colonoscopy and have prescribed following medicines : 1Netazox-of each in morning and night 1Esofag-d each in morning and night 1 Darilong 7.5mg at night 2 Movicol powder sachet a day Looz syrup Please suggest if colonoscopy is really needed or there is some other way as well to get well. As per the doctor, Higher CRP is the inflammation marker because of which he wants to do colonoscopy. Please advice if this is the only way. Is high crp a major risk for my health and how it can be lowered? Any advice would be of great help. Thanks
