While some urethral irritation can occur after kidney stone surgery and stent removal, experiencing burning, blood at the end of urination, and painful erections 20 days later is not typical and suggests ongoing inflammation or a possible infection. Since you have taken antibiotics like faropenem (Faronem) and ofloxacin (Zenflox), and are on flavoxate (Uripil) and alfuzosin (Alfoo), it is important to contact your urologist. They may need to perform a simple urine test or check for localized irritation to help you heal comfortably. Please reach out to them for a reassuring check-up.

Yes, it is generally safe to switch from Alfoo (alfuzosin) to tamsulosin hydrochloride 0.4 mg, as both medications work similarly to relax the prostate muscles and improve urine flow. Many patients transition between them smoothly. However, because every individual responds differently, please consult your prescribing doctor before making this change. They will provide a safe transition plan and monitor you for any temporary side effects, like mild dizziness, to ensure you remain comfortable and your symptoms stay well-managed.

It is not uncommon to experience a fast heart rate after taking Alfoo (alfuzosin). Alfuzosin relaxes blood vessels to improve urine flow, which can lower your blood pressure. In response, your heart may beat faster to maintain normal blood flow?this is closely linked to the dizziness your doctor mentioned. While a heart rate of 100 to 115 bpm can feel unsettling, it is a known reaction and often temporary. Try to stay well-hydrated and change positions slowly. I highly recommend contacting your doctor to share this update, as they can safely evaluate your symptoms and discuss if any adjustments are needed.

At 4.4 mm, your remaining kidney stone is quite small and has a very high chance of passing naturally on its own, especially since you are already taking Alfoo to help relax the urinary tract. Generally, shock wave therapy (ESWL) is not necessary for stones under 5 mm unless you experience severe pain, infection, or obstruction. I encourage you to stay well-hydrated and continue your current medications. Please consult your urologist to monitor your progress.

It is quite common to still experience some burning five days into your ten-day course of Zanocin (ofloxacin) and Alfoo (alfuzosin), as the irritated tissues need time to heal. Please continue taking both medications exactly as prescribed for the full ten days to ensure the infection is completely cleared. Drinking plenty of water will also help soothe the burning. If your symptoms worsen, or if they do not completely resolve after finishing your full prescription, please contact your doctor for a follow-up.

Since the mild pain in your right testicle has come back after finishing your antibiotics and Alfoo (alfuzosin), it is very important to contact your prescribing doctor or a urologist for a follow-up. Sometimes, infections require a slightly longer course of medication, or we may need to investigate other common, non-serious causes for the lingering pain. In the meantime, wearing supportive underwear, getting plenty of rest, and taking warm baths can help soothe the area. Please be reassured that this is a very manageable situation, and your doctor will help you find lasting relief.
