I usually go to the hospital for a four hour IV of Immune Globulin every six weeks to treat my neuromuscular disorder, CIDP ( Chronic inflammatory demyelinating polyneuropathy). Now I"ll try injecting myself once a week subcutaneously for about two and a half hours, which should be safer than an IV. Instead of a large needle in a vein I'll have four tiny insulin sized needles in a fatty area of the skin. I'll be able to walk around while wearing the needles and pump. It will also level out the doses. I pasted some information below. CIDP is: Mine affects both my lower legs and causes me to have many falls and makes it difficult to walk, especially without my leg braces. Right now I'm using a wheelchair and working my way up to a walker. The medication is called Hizentra: Mine is with four needles and it will take a few times for a nurse to show me before I'm comfortable with doing it myself.
