'pinging ' in my legs when i exercise

[Tortington]

i tend to o on long walks and even as a kid when i used to swim a lot i got a 'pinging' sensation in my legs

it doesn't worry me or hurt me in any way - i just wondered what it is

anyone know?

( i like to think of it as calories going 'pop' 'ping' 'pop'

Tight tendons? I get it in my right shoulder sometimes. Like a piece of elastic is caught on something inside...

oh right thanks
