Male 53, I have severe pain when I urinate. It is only in the tip of my penis. It started immediately after I showered. I thought I grabbed the body wash, but used an anti dandruff shampoo with pyrithione zinc in it, to wash myself, including my penis. Is this a temporary discomfort as it would if I got it in my eyes?
Degree understand your concerns went through your details. I suggest you not to worry much. You are right. The burning sensation and discomfort could be just a spontaneous reaction by the sensitive penile skin. Wash it thoroughly with mile soap and the sensation could be better in some hours. Also, EEP the area clean.  Chat Doctor.  This will increase the urine and the urine will wash the inside of your penis. Hope this answers your query. Available for further clarifications. Good luck.
