Hello doctor, i?m suffering from pain/ burning sensation at tip of my penis after urination. I had this issue an year ago and I have done uti, std diagnostics tests, the results were negative and still used antibiotics (prescribed for uti). However, it had been persistent since then on/off and in recent times it has been very severe. Would you kindly evaluate this condition and let me know what should be done before it gets worsen. Thanks in advance!
