Hello and welcome to HCM.
Thank you for your query.
The UTI will require a further culture of the urine, which will help in finding the most suitable bacteria to treat your infection, this will help rid you of your symptoms. Also, a potassium chloride
based solution will help treat the burning sensation and irritation caused by a UTI.
The location of the abscess
is of worry, and could indicate other conditions. The best and most common way to treat an abscess is with antibiotic therapy. Only tough abscesses are treated with a small surgical procedure.
Please visit your doctor to get examined and start on antibiotic therapy, which is the solution to both your problems.
