Hello, Fish bone ingestion should not be taken lightly , please go to the emergency room as soon as possible and get an ENT specialist consultation. Get an x ray done like X ray neck AP and Lateral views and X ray chest with abdomen standing ; to locate the presence of the fish bone. If in the throat and food pipe will need to be removed under general anaesthesia. The fish bone if gets impacted then will cause infection and pus formation. you also might need to get done an endoscopy , this will be decided by your doctor and x ray report. In doubt do reply.
