Can Fungal Infection On The Scrotum Be Treated?

Question : Dear Sir

I am given Dermadew diaper and lulizol cream and onitraz forte and icid L tablet by my dermitologist..I am taking this meds 2 times from last four days and applying creams daily twice and there is absolutely no help..

coming to my problem, in the photos (due to cream. it is white).. I have burning sensation between my scrotum and inner thigh..(there is no itching only burning). if you can see there is cut like mark on my scrotum which when touched or comes in contact then only gives burning sensation (while taking bth or sometime walking because of friction)..I have this problem from last 15 days..I don't think so it is fungal infection but may be multiple small cuts on both sides of scrotum while shaving.( although I don't recognize any major problem while shaving but yes it was burning there 15-20 days before when I shaved but I used to apply prickly heat because I thought it was because of heat but burning sensation started increasing
...little.part on thigh is red but no itching and burning (I believe it is because of heat rash but after using prickly heat powder (I used it before starting this treatment)it is not giving any problem but in appearance it is red) I use very loose innerwear to avoid accumulation of sweats

Do you see this cut like line??(in the image which I added recently) I have it on either side of scrotum..Only when this line gets disturbed (touched or taking bath) I get burning sensation..is it fungal infection only ??
