Yesterday I had Upper Endoscopy and Colonoscopy. Everything was fine. Went home and started with fever all day long. Around 5pm I had no more fever and then I started to have neck pain,throat pain and upper arm pain. And today I have knees, hands, arms, neck, throat,everything hurts. Because of the knees I am having trouble to walk and the hands hurt so much that is hard to open and close. Is this normal after these exams? If so how long should it last?
