Post scabies nodules

Finding this group kinda made me feel less alone , i thought i am the only one going through this! I find it also odd that very few got proper help from doctors, it seems like they’re not really aware of this at all, and i like many, didn’t as well. I discovered i had scabies beginning of December when itching started being a nightmare, and even tho i used Permethrin twice but the itch kept coming and was as intense as the beginning even tho dermatologists ruled out reinfection . Its only when i used Antiscabiosum® 25 %( a cream in Germany) that the itch finally got better and almost disappeared, i still have the urge to itch here and there but its nothing compared to how it was before. And as i thought I’m finally done i started getting post scabies noduls on my penis and testicles. And i didn’t really mind them as i read they would go away alone with time and i was glad i can go with my day to day life normally, but the problem is, they only got worse. I started getting more, they were getting bigger and kinda inflated which hurts a lot since this area is always in contact with fabrics. I tried many moisturizers and saw multiple doctors, they gave me skin repairing creams, anti inflammatory creams and i also tried hypocortisone as it helps with inflammation but nothing is working! Im getting really frustrated and I’m really tired and worried, i wonder till when this would last and i wonder whether others are also going through this . Would appreciate any advice or suggestion!!
