I've now got the spinal morphine pump for my severe RLS\WED.
It is loaded with a very low dose of morphine and I have to take morphine pills to survive, but next week they will inject a higher dose and then a higher again after one week more. After that we will know if it works for me. The pain doctor explains for me that it takes some time for the brain ( my poor poor brain) to learn that the pain killer now is coming from the spinal liquor instead of from the stomach, liver and blood system.
The pump is external until then. I am carrying it in a little bag on my shoulder.
