Hi. Sorry the cathter is so I can be comfortable doing rehab. I went to Cleveland clinic pain program and its full days of physical therapy. My pain was so bad that they wanted to do the catheter. I have pn in my legs but they want to treat it like Rsd though I have no other symptoms but the extreme sensitivity. I fear this catheter cause if no side effects why don't more people have it. I'm going to try something and have another opinion coming up. I need to try something cause my pain is going back again. Hang in there too.
