Pain and redness on Corona of penis. Do?

Hi, I am a guy. I have been having feelings of pain on the Corona of the glans of my penis. Sometimes I get a very itchy feeling on a localized spot of the Corona, to the left of the penis. Most times, the feeling is VERY uncomfortable which makes me have the urge to hold on to my penis. The exact spot giving me the pain in the Corona of my glans is reddened. Occasionally I have a 'hot' feeling on my testicles, and sometimes when I want to sit, I have to be careful, as it feels quite uncomfortable. This severe feeling of discomfort is also sometimes accompanied by itches on My body. I am not sexually active, and have taken urine analysis to rule out STD. I've had a penile staph infection in 2017 through 2018, which made my penis to swell up. I had to apply some topical creams to my penis back then. Please, what do you think I should do? I am often in serious discomfort and I do not have urologists around me to check this out. Will appreciate your help.
