Is this normal for such a small stone?
If your diagnosis of a 3 mm stone was made on sonography, please get a plain CT scan for better evaluation. If the diagnosis remains the same, medical treatment for stone expulsion should be helpful.

I'm 45, male, and have an 8 mm stone. I recently noticed slightly pink urine once, along with some back pain. There's no burning. Should I be worried about this combination?
Your stone needs removal. You have not mentioned the location of the stone, hence it is difficult to advise on treatment modality. Visit a urologist.

I, a 42-year-old male, have been dealing with repeated urine infections along with ongoing prostate-related issues. I completed a long course of Niftas earlier, but the problem has come back. Are there safer long-term options?
Chronic prostatitis is a complex entity with a varied aetiology. Every patient requires tailored interventions and treatment. Follow your treating urologist's advice and be patient.

I'm a 39-year-old male. I woke up with discomfort and slight swelling in my scrotum without any injury. It feels heavy and unusual. What could be the reason?
If the current symptoms include burning micturation and fever, it may be a urinary tract infection. If it persists, visit a urologist.
