A prolonged, painful erection is a rare side effect of alfuzosin (Alfoo) that requires immediate medical care. Please go to the nearest emergency room right away to be safe. Regarding your medication, it is generally safe to stop taking Alfoo immediately, though your weak urine flow symptoms may return. Please keep it paused until you can discuss this with your doctor.

It is very reassuring that your kidney and bladder tests are normal. Since alfuzosin (Alfoo) has not fully relieved your symptoms, you may be experiencing chronic pelvic pain syndrome or pelvic floor muscle tension, which are very common and highly treatable in young men. Sometimes, the muscles around the bladder neck do not relax fully. I recommend discussing this with your urologist. They might suggest a uroflowmetry test to check your urine flow or recommend pelvic floor physical therapy. In the meantime, warm baths and avoiding bladder irritants like caffeine can help soothe your symptoms.

Since Alfoo (alfuzosin) hasn't provided relief, it is very important to consult your urologist for a comprehensive re-evaluation. At 23, these overlapping urinary and bowel symptoms are often related to pelvic floor muscle tension or chronic pelvic inflammation rather than a simple prostate issue. Your doctor may suggest pelvic floor physical therapy, alternative medications, or further diagnostic tests to find the root cause. Please be reassured that there are other effective options available to help you feel much better.

Stopping Alfoo (alfuzosin) or baclofen does not directly cause your penis to bend. These medications affect muscle relaxation, so stopping them can temporarily alter pelvic muscle tone or erection firmness, making a normal, slight natural curve more noticeable. Anxiety and erection changes can also play a major role in how your penis feels and looks. This is highly unlikely to be permanent. I gently recommend discussing this with a urologist to put your mind at ease and check your pelvic health.

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.

Medications like Bacstol (trimethoprim), Betheran (bethanechol), and Alfoo (alfuzosin) can often cause these digestive side effects. Please do not stop taking your antibiotic, Bacstol, without speaking to your doctor first, as completing the course is essential to fully clear the infection and prevent it from returning. I highly recommend contacting your prescribing doctor today. They can safely adjust your treatment plan, advise if you can take them with food, or suggest a mild remedy to soothe your stomach while you finish healing.
