Once they are infected, first aid kits won't help. First aid will clean the wound to prevent infection, but once it's set in (the limb status turns deep green), you are basically screwed unless you find some antibiotics.
Are you sure in the game it's not helping ? because the odd thing is that the "recovering from infections" from the accidental "window battle" happened after i used the 1st aid kits i found, i had not taken any antibiotic at the time.
Now i have taken some antibiotics for the zombie dog horde battle, after the manufacturing of the many 1st aid kits i applied without success, still no "recovering from infection" message, making me wonder if it's too late (it's been only a few ingame hours)
Cauterize it. Use a cutting tool to cauterize a wound, which will consume a match or lighter charge as well, causing IMMENSE pain, but allowing you to clean wounds and even infections with some luck.
Thanks, i'll give a try to this, hopefully it will help where 1st aid/bandage/aspirin/antibiotics seems to not do anything.
On another note, i noticed my save folder is now having more than a thousand of files ?
As i am settled on a small part of the world that i intend to clear from threat, i have not explored much of my world, so are we back at the original save method from the old Cataclysm in which if you explored the world your saved game exploded into several dozen of thousands of files , making it painful for file transfering / fragmentation ?
edit : oh joy, i was wondering why my combat knife near a fire wasn't letting me having the option to cauterize when i activated it, and i noticed on my @ status effect that the "Infected" mention had disappeared ! there's only the "recovering from infection" left there.
I guess something worked , just with more delay than i thought.
Though the wounds are still painful and swollen, regularly taking aspirin to get the level of pain under control and avoid getting too much malus to hit/run/etc...
14 days of survival, my character is starting to get good skills (and thanks to the many books gathered, he should be able to craft/build many things to keep him busy)
Now i hope the zombear season will not trigger again, though with my mossberg i am now confident i could take them out without the bush/shrub/borken window tactics.
