I recently started experimenting with the PA5K and am starting to get serious about using it. However, so far I find that I cannot tolerate more than 24-48 hours in the device. I have a 4G PA piercing, which is about 2 years old and it's been over 6 months since I stretched to 4G. When I put on the device, it feels perfectly comfortable. The pin is just a tiny bit smaller than my usual 4G jewelry. However, when I get hard over and over it puts pressure on my piercing and starts to irritate it. The pain is very similar to what I went through after the initial piercing and each stretching (from 10G to 8, 6, and 4). Nonetheless, after a night of sleeping in the device it often hurts so bad that I have to take it off and put my regular jewelry back in. I plan on repeating this cycle over and over, gradually increasing the time spent in the device until I am totally used to it. But it would be nice to get some reassurance from someone else who has been through this. Did you have success getting gradually acclimated to this device? Will things get better for me or worse?
