I recommended the shower sprayer. You need to remove the dressing. I don't know the location of your incision and packing, but if it gets contaminated when you go, then it needs to be replaced. So remove it, spray it clean, and replace the guaze. I would talk to your doctor -- or his/her nurse assistant -- about how long you have to keep packing the wound. At some point, he/she will want you to stop packing it so it can heal. My doctor said to not pack it, but to place guaze on top if it just to catch drainage. But I am not your doctor and don't know your exact situation, so please call and talk to him/her about it. The nurses are usually easier to get a hold of, and often are caring and compasionate and will talk the time to answer all of your questions.
I straddle the side of the tub when I use the sprayer. I put one foot in the tub and keep one foot outside, and then sit down on the side of the tub. Then I spray away! Very easy. In the beginning when the guaze tends to stick to the wound (OUCH!), I would spray the guaze gently and the water would help it come off easier. Much less ouchy. Then I would use the toilet and then get back on the tub to spray it clean.
You really do need to keep the wound clean. In the beginning, I would wet the guaze with sterile saline before I put it over the wound. The saline helps keep it clean and promotes healing. You can buy sterile saline at the pharmacy, or get your doctor to write a prescription for it so you can get large quantities cheaper. Again, ask your nurse about it.
The beginning is the worst part, so hang in there! You will heal! You will get better! Healing is a slow process, but the body is happy now that the nasty abscess is gone!
