Thanks every one for your replies,
We did mention it to the GP on our 6w check up, and he said nothing to be concerned about, and we also did mention to the MCHN and she didnt really make any helpful comment.
Both the Chiro and DP have said its not as bad any more but i still worry. I might look into getting it checked out again by a diff doc or my usual MCHN (the one i saw was a fill in and no help at all with anything!)
