Hi F.,
I have been there. The thing with the laproscopy is that they really beat you up in surgery. Filling you up with air so they have more room to work and then the instruments in and out of the incisions. It isn't a fun recovery.
Really, time is what will make it better. If you can get up and walk around as much as possible and keep "somewhat" active as I know you can't do a whole lot being only 10 days post-op.
My first child was born via emergency c-section and I have a vertical scar (most are horizontal) and I feel like the laproscopy was a worse recovery.
If you can find those patches that are like heating pads (I think they are advertised for cramps or backaches) and put those on, that may help relieve some of the pain.
With the ultram, I wonder if eating more when you take it would help?
Hang in there. Hopefully other moms will have other tips.
Sending hugs,
B.
