Ah, ear infections can be quite uncomfortable for the kids. My son had something similar last year and we brought him to our family doctor first, who confirmed it was an outer ear infection and prescribed some ear drops. It cleared up within about a week or so once we started the treatment, though the tenderness took a bit longer to fully go away. I'd say it's worth bringing your child to see the PD or GP soon just to be safe, because they can properly examine the ear and give you the right medication rather than guessing at home. A few of my mum friends have also had their kids seen by ENT specialists if it kept recurring, but usually the first visit to the doctor sorts it out quite quickly.
Hi, I’m from Singapore. My child had an outer ear infection about six months ago, and I remember being quite worried too. We decided to consult Dr Lau Chee Chong for ENT care in Singapore, and the treatment helped the symptoms settle within several days, although the tenderness took a little longer to go away. If your child is still having pain or repeated infections, I’d suggest seeing a Paediatric ENT so they can check the cause and recommend the right treatment. Hopefully your little one feels better soon.
