Hello dear, Thank you for your contact to health care magic. I read and understand your concern. I am Dr Arun Tank answering your concern. Pseudomonas is onr of the most resistant bacteria we have in list. I advice you should do culture and sensitivity for it. Once you have sensitivity report in hand you can take the antibiotics which are most sensitive. Please do not give him random antibiotics. As this can not cure, and adverse drug reaction have to face the patient. Once you gave appropriate antibiotics infection will start going to cure. Please take plenty of water. This will help flush the bacteria from the urinary tract. Maintain good local cleanliness. This can be helpful for treating the infection equally as antibiotics do. I will be happy to answer your further concern on bit.ly/DrArun. Thank you, Dr Arun Tank Infectious diseases specialist, HCM.
