Whether or not it is painful to clean earwax in the hospital depends mainly on the way the doctor cleans it, and there may or may not be painful, as follows: 1. However, most patients can tolerate this pain. Of course, children need to cooperate well with the doctor when having their ears cleaned with an endoscope. If the child does not cooperate well, it is best to proceed with caution so that the child does not suddenly shake his head and have eardrum damage.2. No pain: If the earwax is flushed with medical saline, it usually does not cause pain, and this method is mainly for flushing when the earwax has been softened. If the earwax has not softened before, it usually cannot be cleaned up with saline, but rinsing the earwax with saline usually does not induce pain in the ear.
