Query: The gel on these pads turns into slime/goo and caused my skin to itch

These work fine as far as they do a good job of conducting the TENS current. The problem is that the gel doesn't remain gel. I have severe arthritis and have been in constant pain for over 25 years. I use TENS for long periods. I place the pads and then cover with an elastic bandage to keep them in place. Every day I remove the pad, wash, and put the pads in a different position. After 1 day the gel is soft and 1/4 of the time comes loose. After 2 days, the gel is goo, and 3/4 of the time comes loose. By the end of 3rd day, the gel is basically snot and is dissolving all over the elastic bandage. These pads also make my skin itch.. I generally buy whatever pads are cheapest but I have never had these problems before. Never going to buy again.
