Why Does My Penis Hurt Extremely Whenever I Urinate?

My penis hurts extremely whenever i pee and my penis head has become very painful to touch. i was prescribed azithromycin but it seems to have only gotten worse, to the point that i have refused to pee anymore because it feels like someone is slicing my urethra with a razorblade when i try. plus my mouth and tongue has recently begun breaking out and becoming very sore. what could be wrong that the antibiotics couldnt help?
