I have been induced twice first time with gel second with catheter. So I can't inform you of the "increased" pain rather than going into labour naturally. I was induced both times at 37 + 2 for medical reasons. I was informed of the risk of c-section before hand. I was given 2 lots of gel then the drip after they broke my waters, dd1 was born within 4 hours of this with no drugs. People say that you can't move but you can go to the toilet and stretch so your not completely restrained.
Each individual experiences labour differently, there is risks with induction as well as natural labour. The best thing to do is vocalise any queries you have, if you need pain relief ask for it. And just think you will have a beautiful baby that will be all worth the "extra" pain.
