Just wanted to add that besides the possibility of a limb needing to be amputated, a septic infection (which is when the bacteria from your infection enters your bloodstream) the infection can affect internal organs which can lead to other situations and conditions that may kill you eventually, but not before causing much suffering overall.
I say this because my mom who was on dialysis got an infection in the port in her arm where they connected her to the dialysis machine, and that infection spread to her blood (sepsis) which in turn caused what they called "vegetation" on her heart valve/s, which in turn necessitated a few open heart surgeries, to try to remove the vegetation on her heart and then ultimately an artificial valve to replace the damaged one, also the need for meds like blood thinners to ward off clots forming due to the artificial valve. She also always had the possibility of the sepsis returning because they can never be 100% sure the infection isn't still present in the blood and is just dormant, so that worry was always present. If she'd not had the surgeries, or treatment in hospital for the sepsis, her suffering from the sepsis would've been excruciating but yes, it would have indeed killed her. I myself once had cellulitis which they were concerned had already, or would, turn into a septic infection - it didn't, but even so it was one of the most miserable I've felt in my life and i had to be in the hospital for 4 days on IV antibiotics, then longer on oral antibiotics. I just think that there are other, simpler more direct methods than one that could lead to sooo many subsequent medical conditions which will cause you pain, further suffering, worsened quality of life and the constant need for doctors and medical treatments and/or monitoring....and who wants all THAT interference or struggle?
I'm so sorry your current suffering is so intense but please, be kind enough to yourself to not needlessly put yourself through even more pain and suffering. I'm sending you a hug and the hope that you'll find peace somehow in a more gentle way. <3
