My mother is 53+ year. She is suffering from diarrhea and abdominal pain from last 15 days. We did 5 sonography test.in 3rd test we found colitis we gave treatment of colitis for 1 week which include flagyl, zostum and other antibiotics but no use. Case remains same. After doctors suggestion we did ct scan and colonoscopy test and thankfully there is no symptom of cancer in it. After colonoscopy doctor told us it's not cancer. After colonoscopy we again did stool test in this test doctor found amebiasis. Last 2 days we took treatment of amebiasis. We saw effect for 1 day with use loperamide but suddenly today afternoon watery diarrhea started and abdominal pain after diarrhea. Now doctor again asks for stool samples any suggestion or help. Please.
