@semicolon I am sorry about your colon cancer and your liver condition in the past. Now you have diabetes to deal with. That must be difficult. I don’t know the direct role lymph nodes have regarding insulin (if any) but this I do know after 50ish of having diabetes. Having diabetes makes it more complicated to manage other conditions and having other conditions makes controlling your diabetes more difficult. It is a challenging two way street. These things factor in to figuring out insulin dose to achieve a healthy A1C. How long have you been on insulin? It usually takes awhile of fine tuning to get the dose “just right”.
