The incisions have healed, that's 100% (sic) it's having something shoved up your spine the size of Texas is the problem, lol. The battery attached to it (about a hockey puck size) that sits on the belt line makes it very difficult to sit, drive and ride rollacosters (ha, those days are long gone anyways lol). Granted it's doing its thing to help mask the pain, so I'm not complaining, ok maybe a little.
