i think i felt it again today. but this time it was like bubbles popping!
i've worked out that for me the streching feeling starts when i've been on my feet for 5hrs+ and moveing/lifting things makes it harder (as well as running up and down the dept!)

im glad to hear that i am experanceing is "normal" and that i dont have a mutant tadpol in there with blip. *breathes sigh of releaf* thank-you for all your help :hugs:
