Tinea cruris for 8 months. I am broke.

Sir i have tinea cruris i have used several oral medicines and tubes including including terbinafine for 28 day but didnt affect may be coz i was always sweaty. Then i changed doctor and he prescribed itraconazole 200 mg with levocitrizine dihydrochloride and terbinafine plus mometasone at night and sertaconazole at morning. I m on these medication for almost 25 days. But the dark black scars are as it is. I forgot to metion, in between these two treatment i used a salicylic based ointment which gave me a quick relief from the redness,swelling and pain and the black scars developed after that are not changing a bit. What do i do, should i continue the medication as doctor said it would take 8 weeks or i should take a second opinion. And from past 28 days i almost keep myself dry using clomitrazole powder except for an hour when i am at gym and i do take a shower right after gym. I am taking proper hygeine. Please help i am still a struggler preparing for job, i am broke.
