mine got worse each time....I am not going to lie as I was lied to and I was not impressed.
with DD1, nothing
DD2 - paracetomol
DD3 - co-codomol and hot water bottles
DS1 - very strong pain relief needed (I was being sick with the pain), plus hot water bottle and a tens machine (which helped *immensly).
DS2 - I was on stronger pain releif than that given to the CS mums, and still was passing out with the pain, but then, I had retained placenta which they missed and the MW was so very rude, telling me "well, what do you expect, it is your fifth!"...she was very unsympathetic (altho sh apologised LOTS when I was readmitted and needed several D&Cs to get me sorted!).
anyway.....what I am trying to say......yes, they do normally get worse, but if you ensure you have adequate pain relief set up you should manage. and if poss, get a tens machine, as if I evere had anymore, that would be my first purchase.
