I'm 60. My battery is running out in a few months. I had my first one at 42. My second one 51. I have alot of medical problems that cause extreme pain full body neuropathy plus muscle wasting. It started after taking antibiotics. I have seizure disorder controlled, neurocardiogentic syncope that's what the pacemaker is for. Plus sibo and Neurogenic bowels. My whole body has been effected due to toxicity. I also had a botched floroscopy epidural spinal tap which injured me with 8 bulging discs, tarlov cyst and sacral swelling. Does anyone think of no replacement who is sick with other diseases or conditions with no cure ?
