Melody first hello. I am sorry about your husband and the continued struggles. You are an amazing wife. I am clueless but mean well ? is the metronics a pump or the spinal cord stimulator? I thought the pump sends medication through ones system and the scs is what changes the signals and sometimes causes tingling where the pain was. I was suggested though now it is on hold the scs so that is why and also know someone from here who just got one after the trial.
You are so right this is not one size fits all and part of the frustration is what works for one may not for another. Hope you are taking care.
