I had a closed surgery over a year ago, but the scar kept opening, so I finally went to a wound care center. The doctor is making me pack with gauze dipped in dakin solution, but I'm supposed to use saline to rinse the wound out first. Unfortunately when I go to the pharmacy, all I see is an expensive can of saline that has a spray top. I don't know where to find cheaper saline that I can pour into a bottle to use for irrigation. Any ideas? Also, I'm having a really hard time packing the wound myself. It's pretty small, under half an inch, and I can barely get the quarter inch gauze inside. Any tips?
