You mention you don't live in the US, do you mind sharing where you do live? That might make it easier to figure out where you could start looking for wound care, or even someone else would know what steps you might have to take to actually go to a specialist (do you need to be refered by your doctor, or can you find one and make your own appt type things) Was your surgery done at a larger center, like a university or a smaller hospital? MOST if not all hospitals have a wound care team, but larger one definately would have them. IF you travelled over couple hours for the surgery, there might be a center closer to you that has wound specialists, which would be good since you usually have to go pretty often.
Just so I'm not getting you upset thinking the worst, chances are if you had an infection this long, you would probably be having other symptons besides the wound not healing, most likely you would be having fevers or probably would be feeling pretty crappy.
But since it is following a major surgery, I think its always better to be safe than sorry and rule out any big problems
How big are your small sections? an inch or more, or closer to the size of a pimple or blister? What kind of doctor did you go to today? Like Heather asked did they actually do any cultures or swabs to see if there is an infection or just because of how it looked? Since it has been 5 months already I probably wouldn't want to wait much longer to have an ultrasound or any other image testing to see if there is a problem below the surface you can't see. Or try to figure out what if anything is causing problem, They could even do any Xray to see if the problem areas are right above any sternal wires, etc.
I don't know what an ulcer band aid is, but I probably would NOT do any special dressing like the "wet to dry dressing" (packing wound with saline soaked gauze) unless someone from the medical staff told you to. The salt water USUALLY makes the gauze stick to the wound more not less
FWIW we had to do wet to dry dressing on Justin's incision when he was a newborn and it was awful for us and you could tell it was really painful for Justin. It works great for removing the bad tissue, if there is bad tissue that needs to be removed, to help some wounds heal, but You might cause even more problems than you have now. Because how it works is you soak the gauze in salt water (and put it on the open wound that hurts..like the old saying pouring salt in a wound) and as the saline dries, it pretty much attatches to the top layer of the wound and then usually 12 hours later when it is dry, you rip the gauze out and it takes some of the healing wound tissue with it,so reopens it and then you start over putting salt water soaked gauze in the fresh wound.
