I cant wear any earrings other than gold or silver for any length of time or my ears get sore.
They alse get sore (red and hot as described by OP) if I've not worn them for a few days and then try to force slightly lRger shafts in. Like otgers I find germolene (or Savlon cream which has a less strong smell) put on my ears helps and they get better after a couple of days.
The human touch…….flight booking.


I have decided to start wearing earrings again, having not bothered for yonks, apart from special occasions, which seem to be very few and far between.
