May I join the party? Sorry to read you are in pain Polly, I do hope it settles quickly.
We here in Australia have to be careful now, especially my generation (baby boomers). I used to swim a lot and dry off in the sun and fortunately, so far, I do not have any spots but my eldest daughter takes after her father skinwise and has a few dark spots that are being monitored but nothing so far, thank God.
