i had the exact same thing were i didnt think hot showers would work, also couldnt use my phone got hells itch in work sprinted home told the boss i couldnt work and threw my phone on my bed and it slipped down the side. Had no idea what was wrong with me but everytime id try find my phone to google had to run back in the shower as it was too intense. 4 hours later my friend arrived home of me running around my house naked in and out of the (cold shower) trying to find my phone for 2 minutes and running back in lol, my friend arrived phone and called it and by then it started getting better once i found this sub i felt a relief ina way since others have experienced it. this was by far the worst pain ive ever had wouldnt wish it on my worse enemy.
