Please help i am not able to contact doc

It's been like a month or more than a month i had some type of lump or rash (I don't know what that is) on my scrotum it didn't itchy nothing. After sometime, i get more of that on scrotum and it became little itchy at night. After that, i get it on my penis and gets itchy at night. I googled my symptoms and after searching for days i come up with its a scabies or eczema. I've used coconut oil or moisturizer to help with itching. After like 3-4 weeks it gets intense itching and skin becomes way too dry and litlle tiny blister filled with liquid coming on palms, finger,foots and foot fingers. Red pimple like things on thighs and scrotum and penis becoming dry I've used betnovate-n within that period after googling it and their side effects. I used that cream like only 4-5 times in 2-3 weeks, it helps with itching sometimes but it make skin way too dry and scaly. i used permethrin cream on body for 10 hr,skin becomes more dry. please help i am not able to contact doctor. please 🥺
