My father had this procedure and I do notice him sometimes scratching though it's been a few years since his surgery - obviously - I cannot speak from personal experience here but I tend to lean towards the itching being coincidental; also - I would ask your doctor about this.
The metal placed during your spinal infusion might not be the cause of the itching in your body. You might be reacting to another allergic infection depending on what you have been feeding on. Get a doctor to run tests on you to determine the treatment you need.
probably not. titatium is a very inert metal and that's why it's used. do you take pain meds? my oxy's made me ich all over till I got used to them. I was run over while Mtn biking by someone talking on cell/blew a stop sign
