Penis pain

hey guys I need help please 

about 4 months ago I’ve had unprotected sex with two girls in Bali when I was really drunk 

I was really worried about hiv for the first 3 months but all came clear I’ve done all the test for sti and herpes 

and only herpes 1 came out positive 

I’ve taken medicine for trichomonas 

NOTHING IS WORKING 

having random penis pain internally and light redness on my knob I really need advise please 

the pain is mild but is just uncomfortable and gets me annoyed 

Hi T, Is this pain only at erection time or any time?
