That is definitely a possibility. I have been up and about and probably not resting as much as I should. I will just cool it for a couple of days and hope that I everything feels better. Thanks!
It is possible you "overdid it" a bit physically instead of resting? If you did some housework, for example, you may not hurt immediately, but the day after, have a lot of pain in or near the surgical area. The internal healing takes time and if we rush things, we will feel it afterwards. Usually it take a day or two for any pain from "overdoing" to ease. Don't let the exterior of the surgery fool you. Most of the work was done inside and could take as much as, say 10 weeks, to firm up and not be so vulnerable anymore.
