Suggest Treatment For Burning Sensation After Urination

Hello, Last Thursday I noticed a burning sensation when I was urinating. The next morning it was worse and then I could feel some pressure on my kidneys. I went to the doctor and did a urine test, he said it came back negative but gave me antibiotics anyways. I also noticed a small abrasion on the side of my penis after I masturbated on Friday. I went for an std test just to be safe but I still don t have the results. Over the weekend things got worse (more pain in urethra, kidney pressure and I felt exhausted) so yesterday I went to the doctor again. He said to stop taking the anti biotics as they should be making things better not worse. Then I went for another urine test, blood test and x ray. I don t have the results back but last night things started getting much better and then this morning I felt even better. Then later today things seemed a little worse and then when I went to the washroom I noticed the abrasion has gotten worse even though I was not sexually active. I really don t know whats up with me.
