Ive been feeling a vibration sensation at the tip of my penis since yesterday, and sometimes theres inflammation after I pee. A few days ago, I was treated for burning during urination and took antibiotics like Ceftum and Cefixime, but they havent worked. Now Im also experiencing pain in my lower abdomen and back. What could be causing this, and what should I do next?

You may be experiencing symptoms of a urinary tract infection or a sexually transmitted infection. I recommend you start taking a combination of antibiotics such as "Doxycycline" along with "Metronidazole" under the guidance of a specialist. Additionally, you can take "Ibuprofen" 400mg three times a day for pain relief. Make sure to drink plenty of water to help flush out the infection. If your symptoms persist or worsen, please follow up with a healthcare provider for further evaluation and management.
