Has anyone had this?

Im going to go to the docs as its getting worse, i havent told lindsay as i dont want her to worry even tho shes a sister and may have an idea what it is.

Its been happening a while now, the odd flutter but i get it very regular now and when i do it takes my breath away. This has been the only symptom up until recent weeks and i feel so non energetic sometimes. Not so much so that i cant even work as i work hard, but sometimes i jst think ''god im unfit for a 29 yr old'' whcih really in the building trade i cant see as im active all day everyday. So now im worried its linked to the fluttering???

Like i say ill be off to docs soon just wondered if anyone else has had it?
