Thank you for your reply! I grew up with a mother who is Type 1 diabetic and the transition for me was fairly natural and I was very aware of the disease. Having a smart insulin pump has been life changing! As well as when I was working out, it was very easy to keep my blood sugar 90-140 dL/mg. I am fairly well versed in physical therapy and have applied a relatively light regime of isometric holds and stretching. Unfortunately over time, those movement progressively got harder and more painful. I now generally am restricted to walking short distances and 1/4 squat holds, which limits pain and maintains some of my mobility. For some background, I am a mechanical engineer by profession but exercise science has been a passion of mine for half my life!
I did not receive a follow up from my biopsy where the fat necrosis was identified. Upon researching it is generally a delayed reaction to trauma (like falling) or could be triggered by severe blood sugar swings or highs over a long period of time. I have not been injured and I have not been diabetic for long, so the necrosis seems to be a mystery.
