I am a kidney transplant recipient - 4 months - Father donor. Last week I had terrible stomach pain and could not eat anything. The moment I start eating I felt nauseated and stop eating later. I saw an Gastroenterologist nearby and he prescribed me neksium 500 and colospa retard 200 for 3 weeks. It's been one week since I am taking these medicines and now I am completely out of pain and have started eating normally. What I want to understand is, should I continue the medicines till 3 weeks or should I stop them.
