Hello and welcome to HCM. Thank you for your query. From your presentation, this tingling sensation is usually seen in association with a UTI, and should have subsided with treatment along with all the other symptoms. Let us discuss the possible reasons for this sensation still being prevalent. They are: -Right antibiotic used, but inadequate dosage -Right antibiotic used, but inadequate duration -Incorrect antibiotic used In order to avoid all the above mentioned errors and gain complete relief from your symptoms, I would first of all advice a urine culture examination, which provides vital information: -Confirmation of the presence of an infection (still) -The infection-causing organism (bacterial, fungal, etc.) -Most suitable medication which can be used to treat your infection, as you could be resistant to some medications and more susceptible to a few others Next, please consume plenty of water, as this sensation is also seen in normal patients who are dehydrated. The next thing you can do is to add cranberry juice to your regimen, as this helps in getting rid of symptoms such as yours, which are UTI-related. Please also discuss the addition of a urine alkalizer to your treatment regimen (usually a potassium chloride based solution) as this will also help in relieving UTI-related symptoms, such as yours. 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. Best wishes.
