Suggest Remedy For Pain After Colonoscopy

It s been one week....had colonoscopy done with 290mg of propofol, no know allergies. IV was in right hand, BP cuff on left, and i was also laying on left side. All went well until later that nigh....I admit that I didn t eat a bland diet and was very sick, throwing up. But my problem is my throat, jaw, ear, and gland on that side (left), does not hurt to touch. Went i try to work out, or go upstairs, the area starts hurting. Could it be that the med. (propofol) settled or ran thought that area? Could it be gas? When resting, doesn t bother me, but walking upstairs or workout out, it really kicks in, very painful. How long does it take to get out of my system?
