Thank you for your query.
I can understand your situation. It will be good if you share the reports and the medicines that you are having so that we can guide you accordingly. Since your blood sugar is high you must be on some medication and you need to check your blood sugar on a regular basis to ensure that your blood sugar is as close to normal as possible.
Since you have itching and swelling while urinating you need to exclude any urinary infection and/or fungal infection
at the site. This can be done by a clinical examination and a routine urine test.
I hope I have answered your query to your satisfaction.
Wishing you all the best.
