A couple of days ago, my ear was tender to touch, but only hurt when you touched it, now it's ok to touch but it's sore all of the time and several times a day suddenly flares up really badly for a few seconds.
Not being funny bu tI doubt that your parents have access to an auriscope - to look right inside your ear - that's where they need to look. You might have an inner ear infection which they wouldn't be able to see anywhere. GP please.
Just inside the pointy bit that was sore. I'm not sure what the name of the pointy bit is, it might be tragus or something, or is that the kind of piercing you have there?
