In my case the pain stayed about the same once it hit. So I wouldn't be to concerned about what is to come. The meds your on now should do, if you need more you can certainly obtain. The biggest issue to come as Debbie said is the constipation. I too had a very bad day about a week after the constipation started. I would talk to the doctor to give you the proper meds for that and have them on hand so you have them if you need them.
