To treat a urinary tract infection (UTI), you need prescription antibiotics like nitrofurantoin or sulfamethoxazole/trimethoprim, which a doctor must prescribe after a quick urine test. For the joint pain, over-the-counter pain relievers like ibuprofen or paracetamol can help reduce inflammation and ease your discomfort. While joint pain is not a typical symptom of a UTI, it can sometimes occur as your body's natural immune response to fighting the infection. Please consult a doctor promptly to get the correct antibiotic and ensure your symptoms are properly evaluated. In the meantime, drink plenty of water to help flush out the system.

A pH of 8.5 typically refers to your urine, indicating it is alkaline. This is very common and usually not a cause for concern. It can happen due to a plant-based diet, hydration levels, or sometimes a urinary tract infection (UTI). Treatment depends entirely on the cause; if you have symptoms like burning during urination, a doctor may prescribe generic antibiotics like nitrofurantoin. If you have no symptoms, simply drinking more water is often enough. I highly recommend consulting your doctor for a simple urine test to pinpoint the exact cause before taking any medication.
