Hi. That's great that you were able to walk further. They say it takes about 3months for the permanent one to heal. As for the jolts I was told if i had the implant(think it's percutaneous) done by the anesthesiologist the kind that isnt attached to the spine that the jolts could continue, but if i had the scs put in by a neurosurgeon that attaches it to the spine the jolting would stop. Sorry cant remember the proper names. I had a lot of jolting and it was suggested to do the more permanent one attaching to the spine. I opted against the scs but it sounds like you had good success with the trial. Good luck.
