Hello, Kashia, nice to have a nurse aboard!

Calendula 30C, a few pellets in a small bottle of water, sipped a few times a day after surgery
(shake before each dose) will not only help with normal healing of surgical scars, but speed the recovery in general.

For nausea after surgery, the remedy would be Phosphorus 30C, and for retention of urine after surgery, the remedy would be Causticum 30C.

Let us know if you have anymore questions.

Sincerely,
Snoopy
