I had an ELCS last Friday and in the immediate period after I've had very painful trapped wind and for the past few days Diarrhoea and a very upset tummy 
I can't work out if it is the section that's upset my stomach, or the painkillers (paracetamol and ibuprofen). I am trying not to take too many ibuprofen but it means I'm in a lot more pain/discomfort. I can't win!
Anyone else experienced this? Any tips? How long does it last? Feeling sleep deprived and low and it's just not helping matters...
