I'm glad things are starting to take a turn for the better. Be patient with yourself. I think you just might be expecting too much, too soon. This was a major surgery even if you had it lapo and only have a small scar. And, you've probably heard me say before, everyone heals at their own pace.
Keep your chin up. And if taking the meds helps you to relax, then take them. You may want to check in with the doc just to be sure he feels you are on the right track with the bleeding and all.
But be sure that you continue to keep moving. Walking is a really good way to wake up the muscles and work the soreness out. As bad as it hurts tho, it really is helping you in the long run. Or they wouldn't be pushing it in the hospital the day after surgery, right?!!
Good Luck and let us know what the doc says and how you are doing,
