Are there any solutions at the pharmacy to cure a posthitis that won't go away?

Hello, I think I have posthitis. For more than 3 months, I have had a vein inside my foreskin that seems to be more swollen than usual. I have phases where the foreskin is very irritated, sometimes swollen. When I go to the bathroom I have urine drops that come out 5 minutes after I finish. Sexual intercourse is difficult because of the friction which is uncomfortable. I went to see a doctor and he prescribed clotrimaderm, but it was not successful. I went back to see him and he prescribed a cortisone cream, without success either. On my side I tried polysporin and essential oils of theier, but I have no cure again. The doctor wouldn't prescribe me anything else because he says it's not an infection. The situation has been dragging on for months I want a return to normal.
