Dear Dr., I am Vikas Gaur having stomach pain & loose motions since 13 July 2012. I took many medicines & changes 7-8 doctors but neither any medicine is showing any effect nor any doctor is able to confirm me the disease.However all the test has been conducted like CECT scan, endocopy, colonoscopy , antibody , HIV , urine , stool tests etc. All the reports are normal. Only in stool test report it was mentioned about Protozoal Parasits- Giardia Lambia(Cyst). My Current doctor suggest me medicines- Lomotil, Darolac,Tryptomer 25mg, Dortin DS. I was taken this dose yesterday night but today morning I am not able to come out of bed,my eyes are not opening, i am feeling weekness.kindly suggest what to do as my doctor is not picking phone.
