I have been induced twice at 37 weeks and both were really positive experiences.
I was given the gel to induce me and left for six hours for things to get started. During these 6 hours I had no pain at all, I just got very bored.
At the six hour check, I had dilated enough for my waters to be broken. That's when it got painful.....extremely painful.
The first time I was induced the midwife didn't believe that I went from no pain to extreme pain in about 5 minutes so gave me a strong paracetamol for the pain, but as I was only in active labour for 2 hours the pain didn't last long, and DH still jokes about her running out the room for a delivery pack shouting "It's a delivery!" and only just making it back in time to deliver DD1
The second time, I warned them I wanted the gas and air on tap before my waters were broken, and again it was very painful, but active labour was only 90 minutes that time.
Both my inductions were just with gas and air, I had asked for an epidural both times, but at the time I asked I was fully dilated so it was too late.
To be fair I don't think that induction is more painful that normal labour, but you don't have the gradual build up, but then the only "normal labour" I have to compare it with is DS's who was born at 35 weeks (after a 4 hour labour)
