I strongly advise against starting any new alternative medicines without a doctor's guidance. Since your son's ear pain has not improved after 5 days of amoxicillin and dual pain relievers, the current treatment may be ineffective. This could indicate a resistant bacterial infection or a complication. Please take him back to his pediatrician or an ENT specialist immediately for a physical re-examination of his eardrum. They may need to change the antibiotic or investigate further. For temporary comfort, you can gently apply a warm compress to the outside of his ear, but an urgent medical evaluation is the most important next step.
