Aw dear Faye, that's SO kind of you to reply and you're on your holidays as well!! I had a cry myself as I read it, I was so touched that you even took the time to reply on your hols. Ooh fantastic you have been in gorgeous Jersey....I was there for a week many years ago now, but it's such a lovely place and funnily enough I was only thinking back on it a few days ago.
Oh I sympathise completely with you getting that spasm....cor they are blinking agonising! I have had a couple of really bad ones last year and was so affected I just had to lie on the floor in the loo for about an hour, with my husband sitting on the floor beside me. I literally couldn't have got in an ambulance even if we'd called one.(At that time I didn't know what it was, but my GP explained and gave me some extra strong Buscopan to keep on hand in the hope it might help should I get any more. He suspects I just have a really sensitive gut.I have IBS anyway.)
I suppose that person was trying in her own way to help, although that of course depends on her tone and demeanour when she mentioned the exercise/paracetamol, you had to deal with her as well as the spasm she was most likely being 'narky' because her kid couldn't get up the blasted slide! Whatever, her comments will have only prolonged and impounded your stress and so she shot herself in the foot...ha ha!! I find people are SO impatient these days, bet she wasn't from Jersey as all the people especially the drivers were an absolute treat when I was there.
I've been wondering if the back and tummy pain might be adhesions myself. I telephoned the ward at the hospital I was in earlier to see if I could get any advice, but they said eleven weeks since being in the hospital was just too long a gap for me to be called back without my GP referral so if the pains get very bad to come to A&E. Anxious to avoid that long 4 hour wait if possible so will try the GP on Monday.
Its really helped you writing of your experiences, somehow just that reassurance helps me feel like I'm not going barmy! Or being soft. 
Hopefully by now you may be well on your way to being home again, hoping that the sea was wonderfully calm on the ferry. Banish that incident from your mind, bet you've otherwise had a wonderful holiday with your 2 children and husband, one to remember, there are such lovely beaches on Jersey. And bliss no motorways.... Yippee!!
We recently bought two reclining chairs to sit in the garden but haven't yet had a chance to test them out as yet....the really good husband I have needs to get the strummer on that grass!
May I email you instead of writing on the forum? Please don't worry if you'd rather not I do understand. Thank you for replying Faye have a safe and peaceful return journey, will let you know how I get on.
Hugs back,
Yvonne
