Every body is different and tolerance for pain is different. I was definitely uncomfortable as so much movement relies on the core, but not in a huge unbearable pain way. I was given 6 Percocets of which I only took 3 - 1 pill at night just to sleep better as I couldn't sleep on my side and it was not the best sleep on my back. If i needed anything else daytime, I just took tylenol. I did not get crazy pain until week 2 and a half when the pulling in my side nearly knocked me out. However that was remedied with a binder that I wore for just a few days until the worst of it passed. Now at 4 months post-op I barely remember those days and would change nothing.
