I had the SCS Implanted also, and it took a year and a half to try to keep that thing in my Body!!! before my body rejected! Up on my left side of my back I developed a goose Egg, about the size of a golf Ball!! it stayed there for about 6 months, then the skin kind of peeled off like a Sunburn if you will, and then another layer, and another layer, and another until there was a whole about the size of a q-tip. it drained fluid liquid 24/7 clear, no smell we had tested several times for infection but nope it just kept draining, I could stick a Q-tip in it all the way to the end of the q-tip???? Dang! and then where the power/Battery was it turned black???? yeah you guessed it, it started to peel, and then one morning I woke up and I could see the battery silver thingy! my skin had torn open and was a hot mess! Yes can you say emergency Surgery????
