It is in fact some time since I was last injured.
I should remember that it always happens when I get silly about what I think I can do.
About a month ago, I was down in Wales helping my son restore a farmhouse. Charged with digging out a floor, I went at it with pickaxe, shovel and wheelbarrow. I did amazingly well.
I haven’t been able to swim full on ever since.
Whenever I swim free or backstroke, I get a clicking in my left clavicle (collar bone).
I have come to the conclusion that it is bust. It can’t be that bust since I can still swim fly and breast stroke, but I will get medacl advice, and come back swimming after christmas.
