I think mine got worse for the first three, and then got better. They weren't so bad after DD4 or DS. For DD3, I definitely remember the "this is worse than labour and I can't move!" feeling. Not fun. To manage them, I took extra strength acetaminophen and ibuprofen together. Apparently that's not recommended anymore, but at the time, my midwife said it was fine, and it WORKED. There's also something here called Aleve, (not sure what the medicinal ingredient is) that is supposed to be good, and last 12 hours. Perhaps google could help...? Also, a hot pack feels great.

Try not to stress about it too badly - they can really stink, but they do only last a few days, and then they're done.
