Abscess maybe? Does this sound fatal?

I am an intravenous drug user. I inject fetanyl daily. I have not recently injected in my legs but I have both feet. About a week ago I had a sore pop up on my left leg. It is now open and leaking orange grease like fluid as well as yellowish puss. My whole leg is also flaking and peeling tremendously. There are now 3 deep open wounds that all have the same fluid coming out. Two days ago I had it bandaged with gauze which I sprayed with bactine spray and wrapped it with a self adhesive bandage, it was wrapped up for at least 24 hrs. When I unwrapped it the same puss and fluid I explained exploded from all 3 wounds . I have tried to extract the rest of it out but the pain is unbearable. I have no symptoms other then 10/10 pain and I am also in constant withdrawal, and it takes larger doses to come out of withdrawal. It is very difficult for me to walk. Does this sound fatal? The first photo is from just now and the second is from last night after cleaning it with antibacterial soap.
