Hello and welcome to HCM.
Thank you for your query.
It does appear that from your presentation, all your symptoms match that of a urinary tract infection
(UTI). Let me list all the symptoms down for you.
-Increased urge to urinate, but small amounts of urine passed
-Burning sensation while urinating
-Lower abdominal and/or flank region pain
-Itching around genitals
Please note that not all symptoms need to be present to make a diagnosis. Although it is clear, that you are experiencing most of these symptoms.
Now coming to the main and most important part of your complaint. Which is the lack of improvement despite antibiotic therapy. The reason for this could most probably be because the antibiotic used in your case might be ineffective for you. This is quite common as an antibiotic which is effective in one individual can be completely ineffective in another. The reason for this is individual response to a medication.
This can be found with the help of a urine culture and sensitivity examination. This investigation will first confirm the presence of an infection, then provide information on the infection-causing antibiotic and finally information on the most effect medication that can be used to treat you, along with those that you are resistant to.
This will greatly assist the doctor in determining the most suitable medication, which will guarantee results and quick relief. You should start noticing a change by the second day of antibiotics. Please also discuss the possibility of adding a pain management medication and a urine alkalizer solution, which will help relieve you of all UTI-related symptoms.
In the meantime, you should consume plenty of water and also add cranberry juice to your regimen as this has found to aid in relieving UTI-related symptoms as well.
I hope I have succeeded in providing the information you were looking for. Please feel free to write back to me for any further clarifications. I would gladly help you.
