My daughter nearly 9 years ago when she was 11 was given a blood test for the gene deletion I have which causes my HNPP. At that time it was inconclusive , however now shes about to go into her early 20's she has started with the exact same symtpoms I had from many years ago and is in alot of pain with her shoulder when driving , and knees when sitting for long periods , back pain when walking for long periods and hip pain when laying on her side for long periods. She is worried about the nerve conductiom tests I had and being fuelled with strong pain killers if diagnosed. Do you think she has it ? What would you do?
