Hi
@STEELSHARK and welcome to the forums.
I've got to say that looks scary and very painful. Lots of virtual hugs.
Though it may not be a diabetic ulcer I can't help thinking that diabetes may have an impact on how quickly it heals?
We aren't able to give medical advice on the forums so I'm not sure how much help we can be but other members who have had leg/foot injuries may be able to give you insights from their experiences.
Can I ask how recently a medical practitioner has seen your injury and what type of diabetes you have? (If I had an injury like that I would expect it to raise my blood sugars and I would need to adjust my diabetic medication. Are you getting and help/advice on its impact on your diabetes?)
Once more lots of virtual hugs.
