Hello! And Welcome!!!
For me, I am only 20 and so my dr wont give me a pain pump because of my age and if and when I want to start a family he wanted to assure I can be pregnant. SCS and pain pump are totally different, It just depends what works per person. Yes you do get trials of them before. Usually a week long. I knew immediately that it helped. Most people notice immediately with the trial if they get relief, but you get it for a week to see if you like it!
If you read back on posts to lostmary she has a pain pump and has had ALOT of relief!!!
