It was reported that they think something has been wrong with the implantable neurostimulator (ins) ever since the patient had it im planted.The caller stated that the patient has been experiencing electrical shocks coming from the ins battery to the shoulder and up around the neck.The patient's neurosurgeon thought the electrical shocks were due to a pinched nerve, but results of x-ray, cat scan, and mri were negative for pinched nerve.The caller added that the patient continued to experience the electrical shocks after they decreased the ins settings.The caller also said that the patient goes into dyskinesia after they give the patient medicine.The caller stated that the patient has been digressing and experience "convulsion-type effects." the caller also stated that the neurologist told the patient that it looked like the ins was intermittently shutting itself off and restarting.The caller stated that the patient's neurosurgeon is considering giving the patient a steroid injection.The caller stated that the healthcare provider (hcp) told them there were no broken leads, and no evidence that there was anything wrong with the ins.The caller mentioned that an operating room nurse told them there could be a "leaky lead." the caller then stated that the patient has not had their head or chest area scanned yet.Agent did not ask about the circumstances that led to the reported issue.The patient was redirected to their hcp to further address the issue.The caller noticed that the dbs therapy app initially indicated that the patient's ins battery had more than 3 years remaining, then dropped to 2 years, then 3 years, and now it shows more than 4 years.Agent reviewed that the estimated time remaining depends on the last 7 days of ins usage/settings, which can cause the estimated time remaining to change.The caller understood.
