I need medication somehow to cure it, because I did a urine culture on my own.

You received the result of the culture along with an antibiogram that shows which drugs the cultured microorganism (E. coli) is sensitive to and to which it is resistant. These are all prescription drugs (antibiotics), so with the result you should go to the doctor or contact by electronic means of communication presenting the result to get advice and possibly also receive effective and targeted treatment. You will also be asked about your symptoms, other information about your general health is also important. I enclose additional information that may be of interest to you: https://www.gdziepolek.pl/artykuly/zakazenie-drog-moczowych https://www.gdziepolek.pl/artykuly/fakty-i-mity-o-antybiotykach
