Has anyone here gotten sacral nerve modification surgery? If you have please tell me your experience, I can’t find much from people who actually have this implant

Recently one of the doctors I see has been suggesting this as option due to nothing else helping. The majority of my pain is from not being able to void my bladder properly and my bladder thinking there is urine inside when there is very little inside. I’ve been taking oral medications and doing bladder instillations for the past 8 months with little to no improvement. I have had several pelvic exams that showed minor pelvic floor dysfunction. After seeing a PT for a few months they told me I didn’t need to come anymore because the floor dysfunction was so small it couldn’t be causing the pain. The therapy a did improved my pelvic floor function but not the pain. The only thing that gets the pain low enough to sleep is tramadol, seroquel, and valium vaginal suppositories. I take the seroquel for mental health and not as a pain management it just makes me more tired. I take diclofenac sodium 50mg 2-3 times a day, baclofen 5mg 3 times a day, hydroxyzine 10-20mg 4 times a day, lyrica 100mg 4 times a day, the max dose of ibuprofen and tylenol throughout the day, and up to 75mg of tramadol at night. I also use valium 10mg vaginal suppository either whole or cut in two once to twice a day. At my clinic around every other week I get bladder instillations. The medication used are heparin, gentamicin, and bupivacaine. I can’t remember the doses. I think these work? They seem to do best with a consistent schedule but the clinic sees a ton of patients and doesn’t only have 3 nurse appointments open. My doctors are trying to get insurance to pay to have it prescribed for pick up so I can just do the bladder instillations biweekly at home. I already use catheters 3-10 times a day depending on my bladder functionally that day. Even will everything I just listed, I am in too much pain to work like I used to so I am barely paying to bills with the hours I’m managing to actually work. I don’t leave my house except to work because I need to lay down every hour with a heat mat most days. It’s a near constant 6–7/10 of pain, and flare ups with pain so extreme I can do nothing but cry. I eat a full IC diet, I used to be a big coffee drinker, even had my own espresso machine, but I haven’t had any coffee or caffeine since my symptoms started about a year ago. If you’ve had this surgery and it helped you have better bladder function please let me know. I’m scared about getting an implant but because nothing else is working I’m willing to do it. It’s not marketed for pain but instead bladder retention and incontinence, but it seems to improve some patients pain as well.
