Ive had diarrhoea for over 2weeks and worse painful symptoms these past 2 days after completing a course of antibiotics i needed for abscess in my tooth. what can i take to help stop these symptoms?

Get tested: This is either antibiotic associated diarrhea which is treated with hydration, bland,soft diet, kaopectate or Imodium and probiotics or it could be a C Diff infection requiring specific antibiotic treatment as well as hydration, dietary advice, antidiarrheal meds. See your physician for appropriate testing for presence of a C Diff infection.

Antibiotics: Antibiotics will not cure an abscess, only limit the spread of infection ion for as long as you take it. Diarrhea may be due to the antibiotics or to rebound infection. Call yours Dentist for immediate reevaluation (you may need root canal or extraction), the need for an additional course of antibiotics, and a suggestion of OTC probiotics/anti-diarrheals or prescription meds to calm GI tract.
