Hi Spuddle! Long time no talk!! Hope you've been well.
As for the stretchy pains. The only time Ive had anything like that is when I've been pregnant. Are you sure you're not? The pains im talking about are sharp, and usually only last a second, but happen if for example you stand quickly, or roll over in bed too fast etc. It's like a kind of pulling sensation?
Hope you get your answers from the doc. Take care.
