the most important is to get blood sugar down by eating fewer carbs.
And then you need to use your legs, take some long walks if you can or shorter walks, and then don sit all day move, and move at least every 15 minutes in the day time, get up standing every 15 minutes, it also helps blood glucose get down...
but do you actually know anything of how to count the grams of carbs you are eating?
try to count the number of grams of carbs and stay under in total under 100 grams and if that doesn't help do go lower in total...never more than 30 grams in a meal
I see from your first post that you have weight problems.
Can you please tell us a bit more about yourself?
Things like test results, medication you are on, the type of foods you usually eat, if you regularly (or occasionally) test your BG and if so what the results are.
We can give generic advice like trying to modify your diet to reduce carbohydrates but without knowing more detail that is about all we can do.
Lower leg problems and poor healing suggest poor blood glucose (BG) control as the main cause, but I would be guessing there.
If poor BG control is your main problem, treating the symptoms with creams and lotions isn't going to do much good long term. You need to tackle to root cause.
Welcome to the Forum; look around and you will find plenty of (often good) advice.
Regarding your current leg problem... We really cannot diagnose, so you need to get that checked by GP. As others have mentioned, your weight problem, and liking for beer could exacerbate the problem though. I would be inclined to get a proper diagnosis and treatment before the leg problem gets worse, as if the skin breaks you could end up with leg ulcers. Sorry if this worries you, but I am trying to urge you not to neglect this. Please seek GP advice, and do let us know how you get on.
